Fiber enclosure can provide easy-to-manage cabling environments and strong protection for fiber optic cables. Since more and more cables used in today’s data centers, high-density cable management tools also become more popular and essential than before. However, there are so many fiber enclosure manufacturers and suppliers, and the rack mount fiber enclosures supplied therefore available in different sizes and applications. How to choose the rack mount fiber enclosures for your network?

Rack Mount Enclosures Configurations
The rack mount enclosure is generally made for standard 19 inch rack mounting. Depending on the number of connections required, they are available in one or more rack units (RU) height configurations, such as 1RU, 2RU or 4RU, etc. See the picture below, you should choose the most proper one depending on space and port requirement of your network.

Rack Mount Enclosures Mount Types
1RU rack mount fiber enclosures are the most commonly used size in data center server racks cable management. For convenient installation and cable management, there are cover removable, slide-out and swing-out three mount types fiber enclosures to choose from. The cover removable type is an early type of fiber enclosures. If your budget is sufficient, I will recommend you to use the slide-out type or swing-out type though they are more expensive than the cover removable type. But you may get more benefits during installation and maintenance, as they respectively feature a convenient slide-out support tray and an integrated swing-out tray so that you don’t need to remove the whole enclosure from the rack to gain internal access.

Rack Mount Fiber Enclosures Applications
Fiber enclosure has various designs and applications. There are mainly three ways to use the fiber enclosures, which are depended on the accessories that are installed on the fiber enclosure. The following will take a slide-out 1RU rack mount fiber enclosure as example to illustrate the applications of the fiber enclosures in data center. Installed with splice trays, fiber adapter panels and MTP cassettes separately, fiber enclosure can provide cabling environment for different connections.

Application 1: Installing splice tray and FAPs
Installing four fiber adapter panels on the front panel and one or more splicing trays inside the enclosure drawer. This fiber enclosure can provide cable management and protection for splicing joints and connections.

Why Do You Need MTP Pre-Terminated Fiber Solutions?

Today’s modern data center proposition continues to promote the hot topics around consolidation, reduced operating expense, flexibility, scalability and of course being as ‘Green’ as possible along the way. That sounds simple, but when you start to achieve all of the above, maybe difficult than you imagine. Recently, more and more mission critical enterprise networks are considering the need for multiple fibers in a high density, modular and pre-terminated solution. Why are they become so popular? And do you also consider this solution for your network?

Some Changes Occurred in Panel to Panel Links
We have seen panel to panel links, both copper and fiber being installed for many years. These tend to be mainly in data centres, linking up racks, and therefore providing easy moves and changes within local patching fields. But, the trouble is these fibers are terminated and then fixed permanently in to place. In the past, a fiber installation would have involved a good amount of forward thinking, ensuring that the planned lengths were precise as there would be little movement to rectify any mistakes. This would result in a costly installation. Therefore, it’s clear that high speed enterprise networks are already demanding and installing multiple fibers MTP solution, meaning selecting that right easy and expandable fiber infrastructure choice from the offset is of vital importance.

Pre-Terminated MTP Connection Becomes the Hottest Topic
When it comes down to fiber it has to be the pre-terminated MTP connections, providing new advancing technologies that provide multiple fibers in a very small and modular footprint. MTP type connectors, also referred to as MPO, supplying you with a single trunk cable of either 12 or 24 cores. All in all, not much thicker than a standard fiber patch lead, so greatly reduced in size from previous pre-terminated fiber cable installations. However, already being requested are larger cores of 36, 48, 72, 96 or even 144 – but do keep in mind that these will be thicker in construction and could be made of multiple cores on a number of separate cables.

Where Could Pre-Terminated MTP Solution Be Used?
The MTP to MTP fiber cassettes suit various environments, applications and budgets. Primarily, data centres, DR-Co locations, FCoE SAN’s, links between floors/risers and larger communication rooms. Basically, for anyone that needs to quickly create a 10 Gigabit performance fiber network backbone. All of these demand, and would ultimately benefit, from the uncompromised performance, density and scalability that MTP solutions can provide. Additional to the MTP to MTP cassette links, we are also seeing an increased demand for ‘last metre’ fan out cables. For example, 12x LC connections to a single MTP adapter, being used for direct 40 Gigabit equipment links. With the ever increasing need for more bandwidth and virtualisation of application 40Gbp’s speeds are already being installed in data centers.

How Does It All Stack Up?
Supplied as part of the MTP solution is a 1U rack mountable fiber enclosure, so the installation is extremely easy. Each 1U enclosure will hold 3 cassettes and at the back of each cassette you can then access the MTP trunk cable male socket(s). The more cassettes you purchase the more 1U trays are supplied. You will then find at the front of multimode or single-mode cassettes are the legacy LC fiber connections, in either a 6 or 12 duplex (12 or 24 Core), to link back to the active network hardware or existing patch panels. Minimal time is required for the installation, with no need for onsite fiber termination and better still no out of hours working, allowing you to experience the highest performance from your network.

Video Patch Panel With Patch Cable

The jacks commonly used in patch panels in the U.S. conform to Western Electric standard dimensions. The number of insertion cycles a jack can endure should be rated in the tens of thousands. The factors affecting the life and reliablility of a jack include contact wear and failure of the termination switch. Descirable features include the following:

● Contacts fully isolated from the panel.
● Sealed metal housing to keep out contaminants and provide EMI protection.
● Easy replacement from the front of the panel.
● Low VSWR (below 600 MHz)
● High signal isolation (40 dB)
● 75 Ω characteristic impedance.
● Wide designation strips, making it easier to label the field and to allow more flexibility in selecting names that will fit on the lables.

If a patch cable is inserted in the signal path of a timed video system, it will delay the signal by an amount determined by its length and physical properties. The patch thereby alters the timing of the signal path. This can be avoided by using phase-matched normal-through fiber patch panels. The design of these patch panels anticipates the delay caused by a fixed length of patch cable by including that length in the loop-through circuit.

With phase-matched panels, the normaling connection in each connector module includes a length of cable that provides a fixed delay through the panel, usually 3 ft (0.914m). If a patch cord of the same length as the internal cable is used to make connections between patch points, the delay will be the same as that of the normal-through panel. When a fiber optic patch cord is plugged in, it is substituted for the loop cable through the swiching mechanism normally used in normalled patch connectors. Thus, critical timing relationships can be maintained.

In a normal uncompensated patch panel, when a cable is used to patch between two points on the panel, the length of the patch cord is added to that of the cables connected to the patch. The additional cable length delays the signal by approximately 1.52 ns/ft (5 ns/m). To avoid the delays associated with conventional patch panels, phase-matched normal-through video patch panels should be used.

If phase-matched patch panels are used, all of the patch cord must be the same length as the delay built into the patch panel. Obviously, if all of the patch cords must be the same short length for the phase-matched panel, it would not be possible to patch between panels that are separated by a longer distance than the cord can reach. This limitation should be considered when laying out patch panels in a fiber enclosure.

Color-coded cables can be specified. When different-length patch cords are specified, different colors can be used to distinguish one length from another for better cable management.
