TCL UTP cable is best to use, Datang cable for many years been rated as high-tech enterprise, quality credit rating AAA level enterprise, advanced enterprise quality management, performance excellence model advanced enterprises, customer satisfaction enterprises, tax hundred industrial enterprises, large taxpayer. Successful products in recent years the major carriers, many years Sichuan Province brand-name products, supporting the Government recommended products, advanced user worker, customer satisfaction, the best suppliers of quality suppliers, partners, and other outstanding honors. TCL TCL UTP cable type UTP cable using a pair of mutually insulated metallic conductors each twisted part of the way to resist the external electromagnetic interference. TCL UTP cable is more important is to reduce the external interference signal itself. The extent of the two insulated copper wires twisted by a certain density with each other, can reduce signal interference, each wire wave radiation in the transmission line will be another root offset waves emitted. "Lines" in the name is derived from this. Cable generally consists of two insulated copper wire No. 22-26 entwined with each other, when in actual use, the cable has a large number of network cables together wrapped in a sleeve inside the insulated cable. A typical cable has four pairs, there are more pairs of cables in a cable sleeve inside. These we call the network cable. In the network cable (also called twisted pair cable), the different pairs have different twist length, in general, twist length 38.1mm to within 14cm, twist counterclockwise. Adjacent pairs of twisted more than 12.7mm in length, generally denser twisting of the stronger anti-interference ability, compared with other transmission media, cable transmission distance, channel bandwidth and data transfer speed, etc. are subject to certain limit, but the price is relatively cheap. Five lines and five lines, and the latest Category 6 cable, the former and the latter diameter thin diameter thick, models are as follows: a Class 1 cable: mainly used for voice transmission (a type of standard is mainly used in the early eighties Before the telephone cable), different from the data transfer.
