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.

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)

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.
