Fiber Optic Components for Building 10G Data Centers

10 Gigabit Ethernet is a telecommunication technology that can support the network speed up to 10 billion bits per second. It’s also known as 10GbE. As 10GbE greatly increases bandwidth, many companies start to upgrade the data centers to meet their growing needs. How to build a 10G data center? What kind of equipment will be used except the switch? This article will recommend you some basic 10G solutions.

10G SFP+ (small form-factor pluggable plus) modules are hot swappable transceivers that plug into SFP+ slots on switches and support 10G data center. With small form factor, SFP+ transceivers can ensure low power disruption and high port density. Since it’s hot pluggable, the transceiver modules can be added or removed without interrupting the whole network. And SFP+ modules deliver data transmission speed of up to 10Gbit/s, which is 10 times faster than Gigabit Ethernet.

10g-sfp-module

Currently, a wide variety of SFP+ modules can be purchased in the market. For the long distance transmission, modules include SFP-10GBASE-LR, SFP-10GBASE-ER, SFP-10GBASE-ZR, CWDM SFP+ and DWDM SFP+. For the short distance transmission, there are modules like SFP 10GBASE-SR, SFP-10GBASE-LRM. Brands are also versatile such as Cisco, Juniper, Arista, Brocade, etc. To get modules with lower costs, you can pick third-party transceivers which are compatible with these original brands.

Patch cables contain both fiber and copper types. Fiber patch cords, as one of the data transmission media, enjoy great popularity because they have large transmission capacity, strong anti-electromagnetic interference, high security and fast speed. LC fiber patch cord is one of the most common cables for 10G data center, covering single-mode and multimode categories respectively for data transmission over long distance and short distance. To increase panel density, flexible HD LC push-pull tab fiber patch cable is designed. With its unique design, this patch cable allows the connector to be disengaged easily from densely loaded panels without the need for special tools and give users easy accessibility in narrow areas for data center deployment applications. Another special LC patch cord is uniboot patch cord. It utilizes a special “round duplex” cable that allows duplex transmission within a single cable. It’s good for saving cable management space comparing to standard patch cords.

10G SFP+ Direct Attach Cable Assemblies

10G SFP+ direct attach cable (DAC ) is a cost-effective solution for 10G data center. It’s a low-power alternative to optical SFP+ system. The 10G SFP+ cables provide low-cost and reliable 10G speed with either copper cables over distances up to 10 m or active optical cables reaching distances up to 100 m. Because there is no need for spending on fiber optic transceivers and cables. This kind of cables contain 10G SFP+ copper cables, both passive and active and active optical cable (AOC). Active copper cable and AOC are designed for long distance connection, while passive copper cable is for short distance, such as the interconnection of top-of-rack switches with application servers and storage devices in a rack.

Fiber Enclosure

Fiber enclosure is an equipment you must have in data centers. This component is used to provide a flexible and modular system for managing fiber terminations, connections, and patching in high density data center application to maximize rack space utilization and minimize floor space. Fiber enclosure can be divided into different configurations like rack mount (available in 1U, 2U, 3U, 4U), wall mount, indoor or outdoor. The rack mount enclosure come into three flavors. One is the slide-out type and the other two are removable type and swing out type. Fiberstore introduces high density fiber enclosures with 48 ports, 96 ports and even 288 ports loaded LC FAPs (fiber adapter panels) in 1RU or 4RU rack mount for 10G solutions. Or if you already have the unloaded fiber enclosures, you just need to buy fiber adapter panels.

Conclusion

To build a 10G data center, you have to prepare the components, for instance, 10G SFP+ modules, LC patch cables, 10G SFP+ cables, fiber enclosures, etc. You may also need other instruments for testing and cable organization. And all those equipment can be got from FS.COM with higher quality but fewer costs. For more information, you can contact us via sales@fs.com.

Secrets of Choosing Fiber Rack Mount Enclosure

Fiber rack mount enclosures can provide a high-density solution for inter-connects or cross-connects between backbone horizontal cable and active equipment. Enclosures allow for easy field termination of connectors or installation of pre-terminated solutions, and are ideal for high-density fiber applications in data centers, equipment rooms, and central offices. Fiber rack mount enclosures come in different configurations. You may find fiber enclosures in the market with different sizes, slide-out or lid type, fixed front panel or removable front panel, splice tray or preterminated. Among so many types, you have to choose one that suits your application the most. So how to make the right decision? The following will tell you the method.

fiber-rack-mount-enclosure

Which Size of Rack Mount Enclosure?

The rack mount units are designed for rack mounting in 19-in (48 cm) racks. They are available in rack space options of 1U (two panels, cassettes or modules), 2U (four panels, cassettes or modules), 3U (six panels, cassettes or modules) and 4U (twelve panels, cassettes or modules), etc.(See the following picture.) You should choose the most proper one depending on the space and port requirement of your project.

rack-sizes-rack-units

Slide-out Type or Lid Type?

The rack mount enclosures include two kinds. One is the slide-out type, and the other incorporates a removable lid. The slide out type is more expensive while the lid type is less expensive but requires the user to remove the whole enclosure from the rack to gain internal access. If your budget is sufficient, I will recommend you to use the slide-out type. Then you may get more benefits during installation and maintenance, as they respectively feature a convenient slide-out support tray and a integrated swing-out tray so that you don’t need to remove the whole enclosure from the rack to gain internal access.

Fixed Front Panels or Removable Front Panels?

As we know, fiber optic adapters are the key part of an enclosure to accept the various fiber optic connectors. Thus, to choose a proper front panel option is also important. For general rack mount enclosures, there are mainly two types—one type uses fixed 1U High 19” front panel, and the other type incorporates three, or even up to five removable front panels. The latter is now becoming more popular with users, because a plug & play fiber adapter panel solution assures flexibility and ease of network deployment and MAC (moves, adds, and changes).

Splice or Pre-terminated?

Pigtail splicing and pre-terminated assemblies are the two basic way to do fiber termination. Depending on which method you choose, there are some differences in the rack mount enclosure selection. For pigtail splicing, you may need a rack mount panel with fiber splice tray, which are used for efficient management and storage of the spliced optical fibers. Splice tray is used for efficient management and storage of the spliced fiber optic cables. Fiber optic adapters are installed into the cut outs in the enclosure to accept the various fiber optic connectors. Fiber optic pigtails mate with the adapters and the fusion-spliced tails are stored on the splice tray.

But if you apply pre-terminated assemblies, the inner configuration of the rack mount panel is only the spools that are used to organize the cables. Obviously, the pre-terminated solution will help you save more installed time and labor cost.

Conclusion

In this article, you are advised to select the best fiber rack mount enclosure suitable for your own application from so many types. FS.COM offers a wide range of rack mount enclosures, which is good for interconnect and cross-connect in building your data centers. It’s ideal for the organization and protection of optic backbone terminations. Any service need, please contact us via sales@fs.com or call 24/7 Customer Service: 1 (718) 577 1006.

Dos & Don’ts of Cable Management

Just imagine how would you feel when you face cable spaghetti? You must say, “oh, it’s very annoying.” Yes, that’s right. Improper cabling can bring disadvantages like heat retention, untimely hardware failure and maintenance headaches. So how to avoid cable spaghetti and keep network cabling in a good organization?

nice-cabling

Since cable management is one of the most important factors of data center design, it’s necessary to master some cabling skills. The following content will give you some suggestions for cabling installation.

Don’t Pull Fiber Jumpers too Hard

When installing cables, pulling issue can’t be avoided. Pulling cables too hard can damage them by stressing the core. Stressing the core will affect the signal performance. In extreme cases, it will cause unwinding of the twists in the sheath. Under this situation, you should better buy high quality patch cords from reliable manufacturers or vendors. Good patch cords are able to withstand the stress. Because cheap cables have sub-standard sheathing and narrow diameter cores which can cause signal loss. A smaller core is also more fragile and weak, more likely to bend, leading to an increased rate of cable failure.

Don’t Ignore Labels

Cable labels are very likely to be ignored by engineers. After finishing cable installation, they always think they can remember every cable type, including the network cables, power cables, patch cables, etc. Things doesn’t happen like you wish. Your memory will disappear as time goes on. Thus, you should not overlook labeling which can help you identify cables in a short time and leave messages to other installers to easily decipher what goes back.

cable-label

Don’t Forget Cable Ties

Cable ties are cheap and useful to get a clean look of your data center. Today there are many categories in different sizes with many colors. Nylon and Velcro ties are the most two common kinds. Velcro ties are better than plastic ties because they are easy and quick to add, remove and reusable. Nylon cable ties can put mush stress on cable bundles and cause pressure points on the cable jacket, changing the cable geometry and thus decreasing performance. What’s more, Velcro ties can be cut easily to any length you need.

Measure the Exact Cable Length You Need

Usually it says the longer, the better. But it’s another case for network cabling. Improper cable length often causes cable mess. Suppose you have bought 50m patch cable. However, you just use 20m. Then how to deal with the spare 30m cable? Just leave it alone? Of course not. So you’re advised to measure the exact cable length you need. Custom cable is the best solution for you to get the right length.

Leave Space for Cables Trays

What if very long cables are left in your network system? You may consider to put the cables into the cable trays. But it’s not a good idea. Cable trays should not be overloaded. Suspended cable trays are mounted to a rack or something. If it’s too heavy, the cable trays may fall off and break other expensive things. Too many cables is not only safety problem, but also leads to poor operational practices because it’s too hard or fear of disturbing cables. What’s worse, the cables at the bottom of cable try may be crushed and degrade signal propagation.

Choose a Proper Cable Manager

Cable manager is an economical and efficient solution to manage high density structured cabling in data centers and telecommunication rooms, which allows the maximum amount of cables to be organized in a minimum amount of space. Choose the best cable manager which suits the most for your application. Simple or complex cable manager, vertical or horizontal, plastic or metal, one must meet your requirements for network cable management improvement.

Conclusion

Cable management is not an easy work. Some engineers may not take cable management seriously or they don’t care much if there is a little mess. But the improper operation can cause lots of problems. To achieve neat cabling, too many things must be taken into consideration. And some useful tools and equipment are also required. Come to find a perfect cabling solution in FS.COM.

Fiber Patch Panel for High Density Data Center

Fiber optic cable has been increasingly applied to meet the need of high speed network. In data centers, the cabling infrastructure turns to be more complicated. Under that situation, keeping good cable management is necessary since messy cabling will cause fiber optic loss and not easy for troubleshooting. Then fiber patch panels can serve as the tools for cabling systems.

Fiber-Patch-Panel

A fiber patch panel is also called fiber distribution panel. It’s used to terminate the fiber optic cable and provide connection to individual spliced fibers. Besides, fiber patch panels can create a secure environment for exposed fibers, housing connectors and splice unites.

Fiber Patch Panel Types

Fiber patch panels can be divided into two types. Both types can house, organize, manage and protect fiber optic cable, splices and connectors.

One is rack mount enclosure. Usually the rack mount enclosure holds the fibers horizontally and looks like a drawer. Rack mount enclosure is designed in 1U, 2U, 4U sizes and can hold up to 288 or even more fibers. The rack mount enclosures include two kinds. One is the slide-out variety and the other incorporates a removable lid. The sliding design of panels gives engineer easy access to the fibers inside but it’s more expensive. The lid type is less expensive but requires the user to remove the whole enclosure from the rack to gain internal access.

The other is wall mount enclosure. While wall mount enclosure is designed for enclosed wall mounting of adapter panels or splice trays. They are fabricated from steel sheets and finished with a light textured black powder coat. These panels can be easily mounted to any wall using the internal mounting holes. They can protect fibers from dust or debris contamination and organize the cables.

 wall-mount

Fiber Patch Panel Structure

A typical fiber patch panel contains four parts: enclosed chamber (rack mount or wall mount), adapter panels, connector adapters (providing low optical loss connection through mating appropriate connectors) and splice tray (organizing and securing splice modules). Adapters on a fiber patch panel are available in different shapes, such as LC, SC, MTP, etc. Most times, all adapters are of the same type in a panel. But sometimes a panel with different types of adapters is needed when more than one type of fiber optic connectors used in a network.

Fiber patch panel has two compartments. One contains the bulkhead receptacles or adapters, and the other is used for splice tray and excess fiber storage. Patch cable management trays are optional for some patch panels and make possible the neat storage of excessive patch cable lengths.

Fiber Patch Panel Ports

Fiber patch panel ports provide a place for data to enter and exit the panel. The number of these ports vary from 12, 24, 48, 64, 72, 96 to 288 and even more. Actually there is no limit to the number of ports on a patch panel. As long as there is enough room, you can fill the enclosure without interfering with the integrity.

FS.COM offers a 288 fibers 4RU rack mount fiber optic enclosure, loaded with 12 slots duplex fiber adapter panels. This high density patch panel provides a flexible and modular systems for managing fiber terminations, connections, and patching in all applications. With its high fiber densities and port counts, it maximizes rack space utilization and minimizes floor space. This enclosure makes it easy for network deployment, moves, adds, and changes. It’s a perfect solution for engineers to do the fiber termination and distribution.

288-fiber enclosure

Fiber Termination in the Patch Panel

In a patch panel, pigtail or field termination can be used for the connection. If it uses the pigtail approach, a splice tray is needed in the patch panel. This method provide the best quality connection and is usually the quickest. The second method uses fiber optic connector for field termination. A fiber optic connector is directly installed onto the individual fibers. This method usually takes longer time than pigtail but doesn’t need a splice tray in the patch panel. However, the connection quality may not be as good as pre-terminated pigtails.

Summary

Fiber patch panels are very useful especially in the high density data center. They feature with the benefits of easy fiber installation, maximum flexibility and manageability. Although patch panels are attractive, it’s the best only when it fits your application. No matter rack mount or wall mount type, loaded or unloaded, you should better choose the most suitable one based on your own situation.

LC Connector for High Density Data Centers

SC duplex connector was popular a few years ago. But as time goes on, smaller and more compact cabling components are required since the packing density of optical devices keeps increasing, namely high density. The smaller the shape, the more popular the component, just like development history of cellphone. Driven by this requirement, optic manufacturers start to produce mini components. The most widely known is the LC connector, a small form factor connector. The following article will introduce various types of LC connectors in details.

LC small form factor connector has just 1.25mm ferrule, half the size of the standard connector (compared with SC connector). Because of the high density design, LC connector solution can reduce the space needed on racks, enclosures and panels by approximately 50% throughout the network. So LC connector is a good solution for high density data centers. The LC connector uses RJ45 push-pull style plug that offers a reassuring, audible click when engaged. It makes moves, adds and changes easy and saves costs for you. Besides, the protective cap completely covers the connector end, which prevents ferrule end face from contamination and impact and enhances the network performance.

LC Uniboot

LC uniboot connector includes a finger latch release that there is no need for tools when making the polarity change. Some LC uniboot connectors are color-coded and labeled “A” and “B” to provide visual references when making a polarity change. The uniboot design is compatible with transceivers using the LC interface. The LC uniboot patch cords use special round cable that allows duplex transmission within a single cable, and it greatly reduces cable congestion in racks and cabinets comparing to standard patch cords. LC uniboot patch cord is perfect for high density applications. FS.COM LC uniboot patch cords are available in SM, OM3 or OM4 multimode fiber types to meet a wide variety of configurations and requirements.

Push-Pull LC Connector

If you have tried to release LC connectors in patch panels with high density, you must know how difficult it is. As to high density panel, thumbs and forefingers can not easily access to pull the connector. So some manufacturers start to offer a special LC connector which can be easily dealt with. And that’s push-pull tab LC connector.

Push-Pull-Tab-Patch-Cable

LC push-pull connectors offer the easiest solution for installation and removal. The special design is available in a compact model, ideal for minimizing oversized panels. With this kind of connector, you don’t need to leave additional space at the top or bottom to allow room for engaging the latch. The structure of the LC push-pull compact is designed as the latch can be slid back, instead of being pushed down, to facilitate smooth removal. It’s simple for installation and removal. Push-Pull LC patch cable allows users accessibility in tight areas when deploying LC patch fields in high density data centers. Push-Pull LC fiber patch cords are available in OM4, OM3 or single-mode fiber types to meet the demands of Gigabit Ethernet, 10 Gigabit Ethernet and high speed Fibre Channel.

Secure Keyed LC Connector

Secure keyed LC connectors are designed for network security and stability. 12 colors are available in FS.COM, including red, magenta, pink, yellow, orange, turquoise, brown, olive, etc. Connections only work when the color matches. The color-coded keying options provide design flexibility and facilitate network administration. It reduces risks and increases the security of network from incorrect patching of circuits. Secure keyed LC connectors feature low insertion loss, excellent durability.

lc-keyed

Conclusion

This article tells different types LC connectors, including common LC connector, LC uniboot, push-pull LC and secure keyed LC connector. The design of those LC connectors keeps improving to adapt to high density data centers. Nowadays, the trend of network is high speed and high density. So effective cable management is significantly important. And the key concern is how to manage more cables within less space. Thus, among so many kinds of interfaces, LC connector is the most frequently used and the most effective solution for space saving in data centers.

Suggestions for Data Center Design

The demands on data centers and networks are growing very fast. To meet communication needs, more and more devices are connected to the data center network links. It brings difficulties in data center management. The infrastructure design should guarantee the reliable network performance. But how to achieve the best performance? Four suggestions are recommended for you when designing a data center.

Maximizing Network Performance

As today, many companies adopt high density configurations and virtualization to increase the capacity of existing IT equipment. To ensure the network performance, a robust data center infrastructure is necessary. And three parts of the infrastructure must be considered: the structured cabling, racks and cabinets, and the cable management.

data-center

Figure 1. Structured data center

First, the structured cabling performance has a close relationship to the connectivity and cable components. If the components fail to deliver good cabling system, great optical loss will be caused. To improve the channel performance, insertion loss should be minimized especially in 40G and 100G data center. Second, choose right rack or cabinet to accommodate new equipment with different size and weight requirements since active equipment in the infrastructure turn to be broken easily and will be replaced in five years or less. Third, manage the airflow and maintain good cooling system. Because the rising temperature of the data center has an influence on network performance. The last component of the infrastructure is cable management. A well-designed cable management should meet the standards of spare space, high reliability and scalability. The infrastructure is designed for both copper and fiber, maintaining proper bend radius for both copper and fiber, protecting cable from damage, and creating crosstalk and return loss.

Saving Time

Although data center grows in size and complexity, it often requires faster deployment. It must adapt to the rapid changing business requirements. As it says, time is money. Selecting an infrastructure that optimize time, result in faster deployments can save lots of costs.

In order to save time in deployment, installation and future moves, adds, and changes, a suitable modular solution based on the rack or cabinet should be applied. The modular solution is also good for effective airflow management and cooling, which can save time because it can easily support high density when needed. Pre-terminated copper and fiber cabling solutions can also save time during installation and future cabling moves. Pre-terminated fiber systems, for example, MPO to MPO trunk cables or MPO to LC harness cables, can facilitate the migration to higher speeds.

Optimizing Spare Space

To adapt to high speed demands, data center infrastructure turns to be more complex. Now space is a premium in the data center as port densities continue to increase. Considering the cost, infrastructure should be optimized for greater flexibility and scalability. High density connectivity options including high density patch panel, MTP cassette, etc. are the solutions to optimize space while supporting large port densities. For instance, LC connectors (2 fiber) have been replaced by MPO (typically 12 or 24 fibers) connectors for the migration from 10 GbE to 40 GbE and 100 GbE.

MTP-solution

Figure 2. MTP components for saving space

To optimize space in the data center, the following factors are needed to be considered:

  • Choose the rack or cabinet as your basic building block
  • Select racks and cabinets with higher weight limits, sufficient depth and heights that support growing vertically
  • Select cable management that can support existing and future cable density, fluent airflow, and is designed to support both copper and fiber
  • Select connectivity that supports high density and mixed media
  • Use cable with small outside diameter
  • Consider patching outside the rack and cabinet to save space for equipment
  • Select a rack or cabinet solution that easily integrates with overhead pathways
Finding a Cooperator With Rich Experience

During the design phase, the data center design must provide guaranteed performance while providing flexibility and scalability for future needs. During the installation phase, the solution must be easy to install, quick to deploy and easy to manage. So it’s important to find a qualified contractor who has a history of quality installations. You also need to choose a good manufacturer providing cost-effective components covering cooling, power, connectivity, cabling, racks and cabinets, cable management, and pathways, like Fiberstore (FS.COM). And the manufacturer should also have expertise of extending the equipment life, reducing cost and solving other problems in the data center.

Summary

Data center design is not an easy job as the cabling infrastructure becomes more complex for meeting the growing high data rates demands. To maximize the efficiency of a data center, too many elements should be taken into consideration. The above content gives suggestions for data center design to guarantee performance, save time, optimize space, and find an experienced cooperator. Hope this article is useful to your data center design.

MTP Trunks for High Density Data Center

The need for high bandwidth has never stopped. High bandwidth means more fibers are needed for the cabling infrastructure. The demands certainly change the network architecture to be more complicated. For spine-and-leaf architecture, each leaf switch in the network is interconnected with every spine switch. As a result, with leaf-spine configuration in data centers, fiber counts can multiply very quickly compared with traditional three-layer distribution architectures.

Besides, 40GbE and 100GbE grow quickly in the data center. Relatively, the interface of parallel optics like 40G QSFP+ changes to be MPO/MTP with 12-fiber instead of duplex fiber. And that also increases the fiber counts in your data center structured cabling. As data center evolves, links require 144 fibers, 288 fibers or even more. So data center managers are in front of many challenges such as limited space, deployment efficiency and of course the cost.

MTP Trunks Deployment Solutions

To address these challenges, many data center cabling designs use MTP trunks with up to 144 fibers. In data centers requiring more than 144 fibers, multiple runs of a 144-fiber cable assembly are typically installed to achieve the total desired fiber count. For example, if a link requires 288 fibers from the main distribution area of the data center to another location, two 144-fiber trunk cables would be installed. This method can reduce the physical space capacity for future growth. Figure 1 depicts the space savings across three deployment scenarios in a 12-inch x 6-inch cable tray with a 50 percent fill ratio:

  • 4,440 total fibers using 370 x 12-fiber MTP trunks
  • 13,680 total fibers using 95 x 144-fiber MTP trunks
  • 16,128 total fibers using 56 x 288-fiber MTP trunks

comparison

Figure 1. Comparison of trunks with different fibers

MTP connectivity is one of the important solutions used in high density environment. MTP cable allows for the deployment of optical fiber termination of 12 fibers at a time rather than individual termination of single fiber strands. In addition, this kind of cabling is easy for future migration to 40/100/200/400GbE networks using parallel optical technologies. To achieve high-fiber-count cable and connectivity, various implementation options are available.

MTP Trunks

MTP trunk cable assemblies are offered in fiber types in standard 12, 24, 48, 72, 96 or 144 core versions in a compact and rugged micro-cable structure. With high port density, it brings big savings in installation time and cost. Due to its discreet premium connectors and special fiber, it delivers low insertion loss and power penalties in high speed network environment. And the multifiber connector and compact dimension also ease the space pressure in costly data centers.

MTP trunk cables are available in either mesh bundles or distribution fan-out trunks since infrastructure designs, cabling environments and pathway types are different, MTP connectivity in backbone cabling can employ different methods. Below are two possibilities:

Cables that are factory terminated on both ends using MTP connectors (MTP-MTP trunks)
Cables that are factory terminated on one end using MTP connectors (MTP pigtail trunk)

MTP-trunks

Figure 2. MTP assemblies types

MTP-MTP Trunks

MTP trunk assemblies are used where all fibers are landed at a single location at each end of the link—for example, between the main distribution areas (MDAs) and the server rows or between the MDA and the core switching racks in a computer room or data hall, as Figure 3 shows. Additionally, MTP-MTP trunks also appear between MDAs of multiple computer rooms or data halls where open tray is the pathway.

same-computer-room

Figure 3. MTP-MTP trunk assembly deployed in a computer room

MTP Pigtail Trunks

MTP pigtail trunks can be used for environments where the pathway doesn’t allow for a pre-terminated end with pulling grip to fit through—for example, a small conduit space (see Figure 4). This approach is common when needing to provide connectivity between MDAs of multiple computer rooms or data halls. Additionally, a deployment using pigtail trunks can be useful when the exact pathway or route is not fully known, avoiding exact length measurement before ordering of the assembly.

two-computer-rooms

Figure 4. MTP pigtail trunk field terminated in two computer rooms

Conclusion

Many factors should be considered to plan and install a data center cabling infrastructure for actual and future needs, especially in high density environments. So before choose the best cabling installation solution, you need to take following points into concern:

  • Application environment: inside or between computer rooms or data halls
  • Design requirements: traditional three-layer or spine-and-leaf architecture
  • Future proofing: transition path and future-technology support

From this article, high-fiber-count MTP trunks are the best solution for your backbone cabling. MTP trunks is useful for faster installation, lower pathway congestion and greater efficiency while delivering the bandwidth to meet the needs of 40GbE/100GbE/200GbE and beyond.

Purchase Fiber Adapter Panels

Because the laser light is dangerous, and the ends of every fiber optic cable(have a small core) must be encased in some kind of enclosure. So, the enclosure not only protects humans from laser light but also protects the fiber from damage. Fiber wall plates and fiber patch panels are two main types of fiber enclosures.

As previously mentioned, fiber optic cables have a very small core that can be easily damaged if not protected properly. Also, to be consistent with the minimum size of a fiber optic loop and not violate the critical angle, we need to have a way to keep excess fiber optic patch cables, as well as terminated building fiber, neat and protected from damage. Fiber optic wall plates and patch panels allow the cable installer to protect the delicate fiber cable from damage, while still making it useable for the network administrator.

A common device that is used as a fiber optic cable enclosure is called a Lightguide Interconnection Unit(LIU), as showed in Figure 1. The LIU provides a location to terminate individual fiber optic strands into a patch panel, which will be discussed in the next article. A LIU is generally made of galvanized steel that is then powder-coated to provide durability. Most major LIU manufacturers make their devices 19 inches wide so they can be installed in a normal communications rack, If the LIU is to be located in an environment where there is a risk of moisture or corrosives, the LIU can be sealed with gaskets to make it virtually waterproof. Most LIUs have swing out trays in the front and the back to provide easy access to the patch panel to ensure that all loops are a minimum diameter, so the cable will not get damaged and maximum light can traverse the cable.

LIU500x500

Figure 1. Lightguide Interconnection Unit(LIU)

Patch panels for fiber optic cables also called fiber patch panels, which are usually installed into the LIU. Because the core and cladding of two fiber optic cables that are to be joined together must match perfectly, the fiber patch panel must be manufactured to exact specifications and some standard type connector must be used to ensure a good fit. (fiber option connectors are discussed in the next section.) Another fiber patch panel issue deals with attenuation. Remember from the previous article discussed that when you splice or join a fiber optic cable, you can introduce additional light loss or attenuation. The same holds true for the fiber optic patch panel. The connectors on the patch panel should identify the total loss at various wavelengths, and these losses should be added to any other cable loss on that particular cable to ensure compliance with standard and good operation of the fiber optic cable. Figure 2 is a LC adapter panels.

lc_fiber_optic_adapter_panel_6_duplex

Figure 2. LC fiber optic adapter panels

Fiber Adapter Panel (FAP) is used for patching a fiber cable to the enclosures like fiber wall cabinets, rack mounts fiber cabinets or rack mount fiber shelf. It allows you to make quick and easy fiber patch panel connections as they can snap into the fiber optic enclosures easily. Fiber adapter panels are designed to fit fiber optic blank patch panels, rack and wall mount enclosures. To purchase this kind of fiber adapter panels, please visit Fiberstore’s website (www.fs.com).

Several Fiber Adapter Panels

The Conventional Fiber Adapter Plates Need to Improve

Optical fiber has been used as a medium for telecommunication as well as networking because it’s flexible enough and could be bundled as cables. Optical fiber has been especially advantageous for long-distance communications because light propagates through the fiber with little attenuation compared to electrical signals carried by conventional wire cables. Over short distances, for instance networking within a building, optical fiber interconnect cables save space in cable ducts because a single fiber can carry more data than a single electrical cable.

Interconnect cables are generally used as intra-equipment jumpers or patch cords. For example, some typical applications include patching active electronics to nearby patch panels, cable cross-connection on distribution frames, and connecting work area outlets to terminal equipment. Fiber optic patch cords comprise a length of cable with a plug or connector on one, or both ends, and can also be referred to as connectorized fiber optic cables. A patch panel typically comprises a connecting hardware system (e.g., racks, adapter plates, arrays of adapters, etc.) that facilitates cable termination and cabling administration via the use and administration of standard-conforming adapters. (The following figure is a 12 port fiber patch panel)

12 port fiber patch panel

Various fiber optic cable connector and adapter designs can be used to meet the requirements of corresponding Fiber Optic Connector Intermateability Standard (FOCIS) documents. Note that the term adapter, when used in reference with optical fiber, has been defined by the optical fiber industry and standards organizations as a mechanical termination device designed to align and join two like optical connectors.

In some designs, fiber adapter plates provide the means to support and align the interconnection of connectorized fiber optic cables in structured voice or data cabling networks. Conventionally, fiber adapter plates use a metal or plastic plate or support panel having a number of cutouts to accept discrete fiber optic adapters which are typically linked to the adapter plate by screws or clips. Therefore, these adapter plates use a removable attaching mechanism (e.g., screws, clips, latches, etc.) to attach the adapter plate to an enclosure or patch panel.

However, such conventional adapter plates suffer from drawbacks due to the assembly of so many discrete parts. For example, alignment of the connecting optical fibers is crucial to minimize loss across the adapter. While internal fiber optical interface details (e.g., alignment, cable separation, etc.) are specified by rigid standards, the adapter to adapter plate connection is more springy. As a result, excessive tolerances can result in additional mechanical play between the adapter and the adapter plate which can, sometimes, to enable excessive stresses and bend radii of the connecting fiber optic cables.

As a further example, such conventional assemblies by their nature require costly assembly steps. As a cost saving measure, some of the assembly steps can be passed on to the end user. However, this can lead to increasing set up time, having costs of its own, and can result in end user frustration. Furthermore, conventional adapter plate panels are often unlabeled or stamped with labels that are hard for the end user to ascertain, specially when the adapter plate is fully outfitted with adapters and cabling.

It is thus desired to provide fiber adapter plates that improve upon these and other deficiencies of conventional fiber adapter plates.
