Fiber optic racks are preferable in many cases where power lines run in close proximity to the data cables in order to avoid electromagnetic crosstalk to which fiber optic racks are immune. Where there are air conditioning and/or fan motors, which may be necessary for the computer system and are close to the data cabling, the use of fiber optic rack will avoid cross talk interference with the data signals.
Distance considerations are also of great importance in the setup of a computer room data system. With fiber optic rack , we are able to extend the distances that we can run high speed data as compared to copper cables. Where there are legacy copper cabling systems that have to remain in operation, there are media converters which interface the fiber system with MTP 12 fiber mass termination connector ports and also have multiple RJ 45 ports on the front which interface the copper cables. Smaller media converters are also available that interface one or two copper duplex ports on the input and convert the signal to one or two fiber duplex output ports for 10/100/1000 gigabit ethernet systems. By the utilization of these devices, the existing legacy system can be extended to interface more remote systems than previously was possible.
Fiber optic patch panels are mostly mounted in 19 inch relay racks, but they can also be mounted on freestanding rails, in cabinets and also on walls. For fiber optic cabling installation, you should plan the location of your fiber connectivity hardware carefully, including fiber patch panels. You can choose between direct cross-connection and patch panel. It is also necessary to arrange your routing and dressing of your fiber patch cords if you choose to use fiber panels. In the meantime, you also have a choice to use fiber optic rack management brackets to avoid the dangling fiber patch cables.
They are used for horizontal cabling as well as lightwave equipment connections. You should plan your cabling layout carefully to arrange these patch panels conveniently for proper fiber patch cable lengths. These two types of panels should be as close to each other as possible.
In large installations, fiber patch location may have several patch panels. They are usually placed side to side, so that fiber patch cables can cross connect directly without climbing the rails in a route across the top of the racks.
If you have hundreds of copper cables running from servers to switches you may actually impede air flow under the computer room floor. If you are dealing with smaller, thinner fiber optic rack , you do not set up much of a block to your air flow. If you have to go through walls between computer rooms, the necessary holes are much smaller and are easier to fire stop. The weight of the cables held by the track on top of the cabinets is also considerably less and considerably less bulky.
