Rapid development of Web applications increasing demand for bandwidth. Enacted this year Cheap Nike VaporMax UK China , six types of wiring system, with 250MHz bandwidth to meet the most current business applications. However, as technology advances, 250MHz bandwidth is not sufficient to meet the needs of the people is only a matter of time.

Therefore, the development of the next few years the trend started cabling system on the seven types of wiring and cables one is better discussion.

Select cable type cable should be used to require the transmission capacity, bandwidth, price and other aspects taken into account. Types of unshielded twisted pair cable, shielded twisted pair Cheap Nike VaporMax Shoes UK , fiber optic cable three categories.

(1) unshielded twisted pair UTP, is currently the most widely used cabling system for less bandwidth at 250MHz, no special performance requirements of network applications, its overall performance advantage is a good, cheap, construction and maintenance more convenient . Six types of wiring system has reached the limits of performance unshielded twisted pair.

(2) foil shielded twisted-pair FTP, bandwidth is large, strong anti-interference performance Cheap Nike VaporMax Youth UK , with the characteristics of low smoke zero halogen. In contrast, shielded cable prices than non-shielded cable and installation costs are higher, cable bending performance little worse. Six lines and multi-screen system before using this form.

(3) separate shielded twisted pair machining STP, each of the lines has a foil shield, four pairs of wire together, there is a common metal braid shield, which is the standard structure of seven types of lines. It is suitable for high-speed network applications, providing highly secure transmission Cheap Nike VaporMax Womens UK , to support the future of new applications, helping to unify the application of current network routing platform to enable e-mail to multimedia video from a variety of information, all in the same set of high-speed system in the transmission. Extra shielding makes seven types of lines have a larger diameter, these features require installation of routing and termination design space to be especially careful to leave a lot of space and larger bend radius, Corning has now 7 class in China, launched a cabling system.

Back in 1997 wiring standardization bodies and manufacturers have been presented on seven types of copper cabling systems concept, which released in 1997, Corning has 600MHZ seven categories of cabling. It provides integrated attenuation at least 500MHz and 600MHz on the crosstalk ratio of the overall bandwidth requirements of its connector when all the lines in the 600MHz to provide at least 60dB on a comprehensive proximal string around. The super-five system only requires 100MHz to provide 43dB Cheap Nike VaporMax Mens UK , six values in the 250MHz to 46dB. Moreover, because of its excellent shielding design and high-bandwidth, a typical seven types of channels may even be able to provide information on line 862MHz bandwidth for transmission cable TV signal, in another line on the transfer analog audio signal, and then in the third , four-lane high-speed local area network on the transmission of information. This application can not imagine the current, but soon realized by the seven types of cabling systems, launched in the U.S. Corning has seven types of cabling systems leading to a 1200MHz bandwidth.

Compared with the fiber optic LAN Cheap Nike VaporMax UK Sale , seven types of system solution offers the hope of the performance and bandwidth, but the overall cost only a fraction of the fiber. Some people may think that fiber-optic system can bring people enough bandwidth, and cable and wire prices close to the seven categories. However, considering the optical routers, optical switches and optical network adapter cost factor, the fiber will soon lose their price advantage.

(4) single-mode fiber cable, especially for high-speed network transmission, and electromagnetic interference with innate immunity Cheap Nike VaporMax 2019 UK , reliability and support advantages of long-distance transmission, ideal future network transmission medium, its increasingly important. But the cable equipment, materials and termination costs are more expensive, the installation is relatively complicated, so it is generally suitable for long distance and large-capacity wiring. Currently 62.5125 m multimode fiber backbone cabling system has been in the mainstream media wiring in the horizontal system has become increasingly widespread, Corning has now launched a full set of optical fiber cabling system to the desktop, and 5 this year month launched 10G optical cabling system.

The new version of the TIAEIA-568-B.3 provides fiber optic Cheap Nike Air VaporMax UK , fiber optic patch cord to connect the hardware and mechanical properties and transmission performance. Compared with the 568-A, the most significant increase is approved 50125 m multimode fiber, and in addition to SC connectors, also recognized a small component (SFF) fiber optic connector as the connector work area.

Allows the use of SFF connector has brought many benefits to end users, such as, SC connector can not support a larger size device
