A communication line consisting of multiple insulated wires or conductors that form a cable core and have a sealed sheath on the outside. Some also have an outer protective layer outside the sheath. There are various laying methods such as overhead, direct burial, pipeline, and underwater. Divided by structure into symmetrical, coaxial, and composite cables; Divided by function into field and permanent cables (underground and submarine cables). Communication cables have a wide transmission frequency band, large communication capacity, and are less susceptible to external interference, but are not easy to maintain. Capable of transmitting telephone, telegram, data, and images, etc.

Chinese name
