A communication Cable Assembly is a Wire Harness used to transmit signals. A communication cable consists of a plurality of mutually insulated wires or conductors to form a cable core, with a communication line with a sealing sheath on the outside. Some are also equipped with an outer sheath outside the sheath. There are various laying methods such as overhead, direct burial, pipeline and underwater. According to the structure, it is divided into symmetrical, coaxial and integrated cables; according to functions, it is divided into field and permanent cables (underground and submarine cables). The communication cable has a wider transmission frequency band, a larger communication capacity, and less external interference, but it is not easy to repair. It can transmit phone calls, telegrams, data and images, etc.
Communication cable assembly can be classified mainly by cable types and applications
According to the type of cable, communication cables are classified as follows:
1. Single-conductor: refers to the most primitive communication cable, a single-conductor loop, with the earth as the regression line.
2. Symmetrical cable: a loop composed of two identical conductors under ideal conditions.
3. Coaxial cable: The inner and outer conductors on the same axis form a loop, the outer conductor surrounds the inner conductor, and the two are insulated at the same time.
Then they are classified according to the application as follows:
1. Long-distance cable: The transmission distance is long, and it is generally multiplexed. Most of them are directly buried in the ground. In a few cases, they are installed overhead or installed in pipelines.
2. Cables in the city: the wires in the cable are "paired and paired", and the number of pairs is large. Generally installed in the pipeline, a small number of urban cables are attached to the building or installed overhead.
3. Office cable: mainly refers to the communication cable used in the telecommunications office, generally installed on the distribution frame, and some are installed in the wiring trough; the office cable is used between the transmission equipment and the switching equipment in the telecommunications office, and other Inside of intra-office equipment. In order to prevent fire inside the telecommunication bureau, it is sometimes necessary to add a flame retardant sheath to the bureau cable.
