Here are some common patch panel and a reasonable match in the practical application between them.

The late eighties, integrated wiring system has just entered China, then the information transmission rate is very low, only three types of cabling systems (16MHz) products, wiring Barrier terminal block system mainly uses 110 fish skeleton patch panels, mainly are 50 pairs, 100 pairs 300 pairs, 900 pairs of wall-mounted several, while supporting the use of cables; drawback is more troublesome cable termination, termination should not be a one-time change, no shielding products, termination tool more expensive, inconvenient maintenance upgrade. With the continuous improvement of network transmission rates, there have been five cabling system (100MHz), network interface RJ45 gradually to unity, patch panels for terminating cables to transmit data using 19 inches RJ45 patch panel port 110, Such patch back into line using 110 Termination, all RJ45 ports for front jumper wires, which are divided into 24, 36, 48, 96 several, all 19-inch rack / rackmount installation, the advantage of small size, high density, relatively simple and can be repeated termination termination, mainly for the four pairs of twisted-pair termination, shielded products; drawback is due to the line cables in the distribution cat6 patch cable rack on the back of the line termination, and qualifying jumper complete patch management front, so the maintenance and management more difficult; Because the port is relatively fixed, regardless of the number of desktop information to manage port number must be a multiple of 24 and 36 according to the port to configure, the vacancy caused by the wiring ports and waste, not flexible; another relative price 110 fish skeleton patch expensive.
