English name Belden cable network cable called BELDEN CABEL. The company provides cable Belden best price, quality assurance, welcome new and old customers call us cabling project is the most common kind of transmission medium. Belden cable uses a pair of mutually insulated metal wire twisted way to resist another part of the external electromagnetic interference, but the main thing is to reduce their external interference signals. The extent of the two insulated copper wires twisted by a certain density with each other, can reduce signal interference, radio every wire in the transmission of radiation will be offset by the other online radio waves emitted. "Cable" the name is derived from this. Cable generally consists of two insulated copper wires No. 22-26 intertwined together, when in actual use, multi-pair cable network cable from the package together in an insulated cable casing inside. A typical cable has four pairs, there are more on the network cable on a cable inside the casing. 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, counterclockwise twist. Adjacent pairs of twisted over 12.7mm in length, generally the more twisted wire Meech stronger anti-interference ability, compared with other transmission media, cable transmission distance, channel width, and data transfer speed, etc. are subject to certain restrictions, but less expensive. UTP cable: these cables increase the winding density, a high quality insulation jacket, transfer rate of 100MHz, for voice transmission and a maximum transfer rate of 1000Mbps data transmission, mainly used for 100BASE-T and 10BASE- T network. This is the most commonly used Ethernet cables. UTP cable: Category 5 with low attenuation, less crosstalk, and has a ratio higher attenuation and crosstalk (ACR) and SNR (Structural Return Loss), a smaller delay error, performance is greatly improved . Category 5 cable is mainly used for Gigabit Ethernet (1000Mbps). Six cable: transmission frequency of such cables is 1MHz ~ 250MHz, 200MHz when six cabling system integrated attenuation crosstalk ratio (PS-ACR) should have a larger margin, which provides twice the bandwidth over five. Transmission performance over six cabling much higher than five standard, ideal for the transmission rate is higher than the application of 1Gbps. Six with over five an important difference is: improved performance in terms of crosstalk and return loss, for a new generation of high-speed full-duplex network applications, excellent return loss performance is extremely important. Cancel six standard basic link model, cabling standards using a star topology, the required wiring distance: permanent link length should not exceed 90m, the channel length should not exceed 100m. Typically, a computer network using a 3-class line and Category 5 cable, including 10 BASE-T using three types of lines, Category 5 cable 100BASE-T uses.
