Category Cable Manufacturers Introduce The Application Of Communication Cables

Category Cable Manufacturers Introduction Communication cables are cables that transmit telephone, telegraph, fax documents, television and radio programs, data, and other electrical signals. It is formed by twisting more than one pair of mutually insulated wires. Compared with overhead open wires, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and are less affected by natural conditions and external interference.

According to the application, communication cables can be divided into the following three categories:

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 pipes.
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 the intra-office equipment. In order to prevent fire inside the telecommunications office, it is sometimes necessary to add a flame retardant sheath to the office cable.
