Fiber Patch Panel Termination

It seems that we have already known that the fiber patch panel is the bridge of fiber patch cables. Fiber patch panel, also known as fiber distribution panel, serves as a convenient place to terminate all the fiber optic cable running from different rooms into the wiring closet and provides connection access to the cable’s individual fibers. Fiber patch panels are termination units, which are designed with a secure, organized chamber for housing connectors and splice units.

How Does Patch Panel Termination Units Works?

We know that there are two major termination solutions for fiber cable: field terminated and pre-terminated. The pre-termination, with most devices terminated by the manufacturers in advance, requires less efforts when installing than field termination does. Therefore, this post is going to offer a glimpse into the field termination which describes the termination of the fiber optic cable in the field or the termination after installation.

Fiber Patch Panel Termination Procedure

In the termination process, the fiber optic cable need to be pulled between two points, then connectors will need to be attached and then connected to a patch panel. In addition, before they can be attached to a panel, connectors need to be attached to each individual strand, and a variety of tools will be needed. With field termination, we can determine the cable length accordingly, and fiber optic bulk cable is very easily to pull from either end of the installation circuit.
To carry out the termination, such tools are needed as fiber optic enclosure, fiber cable, patch panel, cable ties, connector panels, permanent marker, fiber optic stripper, cleaver, metric ruler and rubbing alcohol.

To terminate the cable, first slide the boot onto the fiber. Strip the fiber to at least about an inch and a half . Place a mark at 15.5 mm for ST and SC connectors or at 11.5 mm for LC connectors. Clean the stripped fiber with an alcohol wipe and remove any debris. Set the stripped fiber into the cleave and cleave it. Insert the cleaved fiber into the rear of the connector until the mark align with the back of the connector body. Slight the boot up and over the rear of the connector body. After the termination, transmission testing of assemblies need to be performed.

In the final fiber patch panel termination, first, open the front and rear door of the patch panel, and remove the covers. Remover the inter stain relief bracket. Second, use cable ties to put the cables on the bracket. The fibers should be put inside the clips on the tray to segregate the fibers from A and B slots. Put the patch panel into the panels clips. Take the excess fiber slack into the slack management clips. Make a bend in the fiber to maintain slight pressure on the connection.

Conclusion

The processes in the device connection and cable management are linking with each other that missing any or failure in any one will result in the imperfect system, or even the damage. If we own a fiber patch panel, we should make full use of its termination function. The products provided by FS,COM enable you to perfect your cabling system.

FHX Fiber Optic Enclosure With Distinct Features

As is known to all, an ordinary 1U fiber optic enclosure can contain at most 96 fibers. As a result, the more fibers you want, the higher enclosures like 2U and 4U you should choose. Given this, we have fixed our eyes on the hot issue and eventually launched the FHX fiber optic enclosure.

Horizontal and Vertical Cable Management At a Glance

When the fiber patch panel is loaded with cables, your cabling is almost finished with the core elements all ready. You can achieve fast and smooth Ethernet connectivity. But turning around, you may find a mess caused and left by the installation. The slack cables without careful comb are hung casually, resulting in a sloppy look just like the noddles being stirred. If we have a look at an expert, it is common to find that they all manage their cables in a good order. And today, we will reveal the secret of the marvelous layout — horizontal and vertical cable management.

Horizontal and Vertical Cable Management

When you try to simulate others’ cabling system, you will inevitably find that the cable management comes in two varieties, horizontal and vertical. When installing cables in a fiber enclosure, you will undoubtedly have to run them both vertically and horizontally. The best solution for this cabling is to run all the cables horizontally from the server directly to the vertical cable management rack.
With these two solutions, you can gain many benefits like enhanced availability through reduced downtime, and improved system performance through reduced crosstalk and interference. We all know that crosstalk is harmful and will damage more or less the data transmission. What’s more, it enables us easier and safer access to individual components so as to achieve improved maintenance and serviceability. And the moves, adds and changes will be simplified.

Horizontal and Vertical Cable Manager

With horizontal cable managers, the cables from equipment in racks can be routed neatly and properly and away from damage. If you are using flat-faced patch panels or network switches form which cables come above or below, horizontal cable manager will complete the support pathway for patch cords between the cabling section and the exact connection point (port) on the patch panel or switch. Alternately, horizontal management can be used to create rack-to-rack pathways for patch cords. The FS.COM finger duct horizontal cable manager is designed with flexible fingers, rear pass-through holes and a removable cover. It can be mounted to standard 19 and server racks and cabinets providing well-organized cabling quickly and easily. 1U and 2U versions are both available at FS.COM.

horizontal cable management

Vertical cable manager just as seen in the below image, utilizes the additional space at the both sides of the cabinet to manage the slack from patch cords, and make sure that they can easily route the largest cable diameter in your plan. For static environments, you can consider installing another vertical cable manager behind the racks, which does not block access to components in the space between the racks. Vertical racks can be also installed under a desk or against a wall and accommodate networking equipment up to 4 RU. Its dual sided fingers enable both front and back well-organized cabling.

vertical cable management

Conclusion

With horizontal and/or vertical cable managers, the human errors which may be committed previously due to the confusion of a mess of cables can be easily prevented in horizontal and vertical cable management. Once you have to deal with fiber and copper cables at the same time, apart from our multimedia modular panel, FS.COM cable managers can be used to house and organize fiber and copper cabling while keeping separation between the two.

48 Port Patch Panel—Best Choice

As we have learned before, port density is a critical concern when choosing a patch panel. Usually the patch panel with more ports enables more connectivity. Common patch panels are always designed in 12 or 24-port configurations. Does it mean that the more ports one patch panel has, the better it will be? However, as far as I am concerned, it may not always be versatile because more ports means more money. Sometimes you just want a patch panel for household use, then a 128-port patch panel is a waste and you need to take care of the ports idled. If you haven’t determined which system you will apply it to, a 48 port patch panel may be a good choice.

Benefits of 48 port patch panel

In fact, a 48 port fiber or copper patch panel is totally enough for home and office use. And the fiber patch panel also has two types as singlemode and multi-mode one. And the advantage of using a 48 port patch panel is that it allows manual monitoring, testing, switching, routing, and other maintenance to be handled quickly because the cables in the front that connect to the more permanent cables in the back are configured and made so that changes can be made quickly and easily when needed.

48 Port Copper Patch Panel

With the copper patch panel, each pair of wires has an independent port. So copper patch panels offer simple and efficient interconnection in Ethernet applications. And when the front copper touches the copper in the back, a little bit of the signal is lost but not enough to worry about. Take the HD-48P-E1U 48-Port 1U Rack-Mount UTP Blank Keystone/Multimedia Patch Panel as an example, it manages and organizes the cabling in your network. The rear cable manager keeps cables neat, tidy and efficiently organized on the back of the panel. Ports are clearly numbered to help you identify connections.

Both the copper and fiber patch panels can provide you with flexibility and scalability, because the network can grow and change on-demand, without the costly, labor-intensive hassle of replacing channels end-to-end. For more information about fiber and copper patch panel, you can refer to this Which One to Choose? Fiber or Copper Patch Panel.

Singlemode and Multi-mode Fiber Patch Panel

The fiber patch panel, 96 Fibers, 48 Ports LC Duplex 9/125 Singlemode Fiber Adapters, 1U High 19″ Fiber Patch Panel from FS.COM, offers the highest port concentration and bandwidth over high performance structured cabling to all network areas, whether in the data centre or in the high performance LAN. By managing varying port densities and speeds in a single high-density patch panel, you save valuable rack space, helping to lower data center costs.

singlemode patch panel

And the 96 Fibers, 48 Ports LC OM3/OM4 Multimode Adapters, 1U High 19″ Fiber Patch Panel can be used as a junction for 50/125 Multi-Mode Fiber with LC connectors. The panel fits a standard 19″ rack, and the LC connectors are standard sized too. Its high-density and easy maintenance allow a low initial investment cost. With it, you can only buy the devices you need now, while leaving room for future expansion.

multi mode patch panel

Conclusion

In a word, a 48 port patch panel makes it easy to organize the fibers in an business or home network.With a 48 port fiber patch panel, you can achieve a better cable management. Of course, one could skip the patch panel and just connect all connectors directly into the hub, however, you need to label the patch panel so you know which room the cable run goes to. But it is tougher to read than labels on a patch panel and also there is risk of having the cable labels fall off. All I want to inform you is that a 48 port patch panel is not expensive in FS.COM.

Wall Mount VS Rack Mount Patch Panel

Patch panels are termination units, which are designed to provide a secure, organized chamber for housing connectors and splice units. Its main function is to terminate the fiber optic cable and provide connection access to the cable’s individual fibers. Patch panels can be categorized into different types based on a few different criteria. Last time, we have shed light on the copper and fiber patch panel and now let’s learn a different pair of it, namely wall mount patch panel and rack mount patch panel.

Wall Mount Patch Panel

As the name suggests, wall mount patch panel is a patch panel fixed on the wall.The wall mount patch panels are designed to provide the essential interface between multiple fiber cables and optical equipment installed on the customer’s premises. The units offer networking and fiber distribution from the vault or wiring closet to the user’s terminal equipment.

This kind of patch panel consists of two separate compartments. As shown below, the left side is used for accommodating outside plant cables entering the building, pigtails and pigtail splices. Whereas, the right side is designed for internal cable assembly networking. And both sides have a door secured with a quarter turn latch.

Rack Mount Patch Panel

The rack mount patch panel usually holds the fibers horizontally and looks like a drawer. Rack mount panel is designed in 1U, 2U, 4U sizes and can hold up to 288 or even more fibers. They can be mounted onto 19″ and 23″ standard relay racks. The rack mount enclosures include two kinds. One is the slide-out variety and the other incorporates a removable lid. As for the latter one, the tray can be pulled out and lowered to 10 degree working angle or even further 45 degree working angle to provide ease of access for maintenance or installation work.

Wall Mount VS Rack Mount Patch Panel

  • Installation

When installing wall mount patch panels, users need to leave at least 51mm additional space on each side to allow opening and removing the doors. Although it can be easily mounted to the wall by using the internal mounting holes, four screws are required when it is attached to a plywood wall, expansion inserts with wood screw for concrete walls and “molly bolts” for sheet rock. However, the installation of a rack patch panel just needs four screws without drilling the wall.

  • Space Occupation

Thinking from another perspective, the advantage of wall mount patch panels is that they allow you to optimize your work space by keeping equipment off floors and desks,which is superior to the rack mount patch panel.

  • Application

Both panels can be applied to Indore Premise Networks, Central offices (FTTx), Telecommunication Networks, Security Surveillance Applications, Process Automation & Control, Systems and Power Systems & Controls, while the rack mount patch panel has an advantage over the wall mount patch panel in that it can be applied to Data Centers.

Conclusion

To sum up, patch panels are available in rack mounted and wall mounted and are usually placed near terminating equipment (within patch cable reach). Both types can provide an easy cable management in that the panel ports can be labeled according to location, desktop number,etc. to help identify which cable from which location is getting terminated on which port on the patch panel, and changes can be made at the patch panel. The world-wide renown FS.COM can provide you the best quality rack mount and wall mount patch panel. Buyers are welcome to contact us.

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.

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.

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 fiber 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 optic 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 usable for the network administrator.

Overview of Fiber Enclosure

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.

What Is Fiber Adapter Panel (FAP) and How to Use It?

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 the standard and good operation of the fiber optic cable. Figure 2 is an LC adapter panel.

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 panel is designed to fit fiber optic blank patch panel, rack and wall mount enclosure. To purchase this kind of fiber adapter panel, please visit www.fs.com.

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.
