Status of wire and cable industry

Wire and cable industry is the second largest industry in China, second only to the automotive industry, product variety to meet the rate and the domestic market share of more than 90%. In the world, China's wire and cable output has surpassed the us to become the world's largest cable producer. With the rapid development of China'swire and cable industry, the growing number of new enterprises, the industry overall technological level has been greatly improved.
China's sustained and rapid economic growth, providing a huge market space forwire and cable products, the Chinese market strong allure, makes the world all eyes focused on the Chinese market, in the reform and opening to the outside world in short decades, huge production capacity of China's cat5e LAN cable industry formed to make the world with admiration. As China's power industry, data communications, urban rail transit industry, automobile industry and shipbuilding industry scale unceasing expansion, the wire and cat5e patch cable demand will grow rapidly, the future electric wire and cable industry has huge development potential. In 2008 November, our country to cope with the world financial crisis, the government decided to invest 4 trillion yuan stimulating domestic demand, which has about 40% for urban and rural power gridconstruction and transformation. National wire and cable industry has a good marketopportunity, around the wire and cable enterprises to seize the opportunity, meet the new round of urban and rural power grid construction and transformation.

12 port patch panel uses

MDF is positioned in front of the central office of information points modular device management. The front of the information point cable ( Cat5e or 6 cable ) into the equipment room after the first into patch panels, patch panels will hit the line modules , patch panels and switches then connect a jumper (RJ45 interface) . Overall , 12 port patch panel  WISDOM telephone connector is used to manage the device , for example, if there is no patch , direct access to the front of the information points to the switch , so that once the cable problems, faced to rewiring. In addition, the management is also a bit confusing, multiple plug may cause damage to the switch port. MDF exist to solve this problem by replacing the jumper to achieve better management.
Dosage and overall network is mainly based on the WISDOM terminal block  number of points or the floor ( and similar floor , depending on how the system is designed diagram ) points to the number of network configurations . 12 port patch panel different buildings , different system designs , patch panels are the main differences between the devices . For example, a building only four rooms , the master device is set on the first floor , all floors between network points are entering the device , then the patch is equal to the number of the building all network points / patch panel port number ( 24 mouth, 48 , etc. ) , plus got to margin ; If, on the 9th floor of a  WISDOM cat5e patch panel building has a room , the master device is set on the fourth floor , then in order to avoid long cable , it may partakers devices are located on each floor , and there is exchange equipment . So the main distribution frame between devices on the network is equal to the number of points / patch panel ports ( 24 , 48 , etc. ) 4 layers.
