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.

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.

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.

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.

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.

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.

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.
