When opening the network cabinet, it will be found that the integrated wiring products inside, in addition to the network cable and module, the other may not be clear, what is the distribution frame, jumper frame and line rack, what is the difference between them? What does it do?
· Line handling frame
Cable rack, some places called cable, is a kind of convenient arrangement of network cable, is used to sort out the network cable, and there is no direct relationship with the network. When the cable rack is installed, the cable should be handled according to the direction of the cable, so as to form a system that is easy to maintain.
The cable frame is generally used with the distribution frame to facilitate the management of the jumper. The cable rack lifts the cable, and the jumper joint enters the RJ-45 module horizontally, so that the cable does not turn at right angles before being inserted into the module, which reduces the loss of its own signal and reduces the radiation interference to the surrounding cables.
Line rack according to the material can be divided into metal line rack and plastic line rack. When using, you can choose according to your own needs.
· Jumper frame
Jumper frame is composed of flame retardant modular plastic parts, which is equipped with a number of toothed strips for terminal wiring. 788J1 special tools can be used to "press" the wire pair to the jumper frame in order to complete the termination of voice trunk cable and voice horizontal cable. Commonly used specifications are: 100 pairs, 200 pairs, 400 pairs, etc.
Jumper frame, often used in large network cabinets, like the possibility of family or small office use are relatively small. The main role of the jumper frame is to reduce the loss of network equipment interfaces such as switches. Because the jumper looks like rows of fish bones, also known as fish skeletons, it is generally used for telephone connections.
The function of jumper frame is to provide a convenient and fast termination method for high-density voice and data cable connection. Jumper frame can be used for both wall mounted machine and vertical cabinet. The scope of the jumper is very wide, suitable for all voice communication systems, multimedia and other aspects of high-speed applications.
· Distribution frame
The distribution frame here generally refers to the RJ45 distribution frame, also known as the network distribution frame. It is used to manage the most important components in the subsystem and is the hub to realize the cross connection of the two subsystems of vertical trunk and horizontal wiring. The distribution frame is usually installed in the cabinet or on the wall.
The use of distribution frame is more popular now, whether it is home or office. Or building construction, as long as the use of the network, will generally use the distribution frame, is to facilitate management.
