The distribution frame is the most important component in the floor management room system, and it is the hub that realizes the cross-connection of the two subsystems, the vertical trunk line and the horizontal wiring. Patch panels are usually installed on cabinets or walls. Category 5 distribution frame mainly refers to the distribution frame that specifically meets the gigabit transmission performance

Category 5 distribution frames are mainly used for gigabit networks. Manufacturers advocate them. Now they are also commonly used in local area networks because they are not much more expensive than Category 5 cables. The current Category 6 distribution frames are generally used for ATMs. In the network, the company LAN is not recommended for the time being. At present, the common type of super five or six patch panels in general LANs, especially the current super five and six patch panels can easily provide 155Mbps communication bandwidth, and has the potential to upgrade to gigabit bandwidth, so , Has become the first choice for today's horizontal wiring. The patch panel can be divided into: shielded patch panel and unshielded patch panel. Most local area networks use unshielded patch panel (UTP—Unshielded Twisted Pair) as the transmission medium of wiring for networking.
