About communication cable
According to the type of cable, the communication cable is classified as follows:
1.single wire: refers to the most primitive communications cable, single-wire loop, with the earth as a regression line.
2. Symmetrical cable: It consists of two wires that are identical under ideal conditions.
3. Coaxial cable: The two conductors inside and outside on the same axis will form a loop. The outer conductor surrounds the inner conductor and both are insulated.
Application category
According to the application, communication cables can be divided into the following three categories:
1. Long-distance cables: long transmission distances are generally used for multiplexing, and most of them are directly buried underground. In rare cases, they are installed by overhead installation or installed in pipelines.
2. Cables in the city: The wires in the cables are “double pairs” and they are many. Generally installed in the pipeline, a small amount of local cable is attached to the building or installed overhead.
3. Local cable: mainly refers to the communication cable used in the telecommunication bureau, generally installed in the distribution frame, and some are installed in the cable duct; the office cable is used between the transmission equipment and the exchange equipment in the telecommunication office, and other Inside the office equipment. In order to prevent fire in the telecommunications bureau, it is sometimes necessary to add fire-retardant jackets to the office cables.
According to the above classification method, the communication cable can be a symmetrical cable or a coaxial cable.
