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 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;... 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 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 PCB spring terminal block 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 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. Today, the rapid development of network technology and the transmission rate, the emergence of Gigabit / Gigabit Ethernet technology UTP (100MHz), six (250MHz) cabling system launch, the other users on the network system application proposed a variety of needs , such as the network (shield), the external network (unshielded), voice, fiber to the desktop, etc., face more functional and flexible information management port on the wiring system of diversification, flexibility, scalability and other properties proposed higher requirements, like Schneider Electric and some other manufacturers introduced multimedia wiring patch panels, adapted to the modern network communications applications for wiring systems. Such abandoned the previous patch fixed patch panel port RJ45 port type 110 can not be fixed weaknesses change, which itself is a standard 19 inches wide, empty patch panel 1U high, on which can be any configuration over five, six, seven classes, voice, fiber optic and shielded / unshielded cabling products, 1U high up Configuration 24 Data copper or fiber ports and 48 voice ports, fully reflects the diversity and flexibility of wiring, upgrades and expansion has brought great convenience; due to its use of independent modular plug in terminal block configuration, patch panels Each port port-one correspondence with the information on the desktop, so when configuring the patch panel without having to press a multiple of 24 or 36 ports to configure, so it will not cause the vacancy and waste wiring ports; addition of such wiring mounting bracket, maintenance, management are positive operation, greatly simplifying procedures; You can also configure the system shielded and unshielded wiring in the same board is that it is different from the old patch of another major feature. Currently voice communication is also undergoing a huge transformation, usually well-known analog phone system is gradually being new digital communications system eliminated, such as the latest VoIP technology, in addition to the popularity of some four-core phone, but also the voice wiring system changed. part cabling manufacturers have introduced a voice IDC RJ45 port patch panel, its way back with IDC termination of voice Multi-pair cables with RJ45 ports for front line management, relative to 110 fish bone patch It has terminated simple, repeatable terminations, installation and maintenance of low cost, RJ45 port wiring simple, fast, clean and the overall appearance of the advantages of MDF.
