Communication cable is the cable that transmits telephone, telegraph, fax documents, TV and radio programs, data and other electrical signals.Consists of more than one pair of insulated wires twisted together.Compared with overhead open wire, communication cable has the advantages of large communication capacity, high transmission stability, good confidentiality, less natural conditions and external interference.

Communication cable: a communication cable made up of several wires or conductors insulated from each other and an outer sheath protecting the cables from moisture and mechanical damage.The photo of communication cable is provided in figure 1.Where the environment is particularly harsh, a protective layer can be installed on the outside of the communication cable sheath when necessary.

A communication line consisting of a plurality of mutually insulated wires or conductors and having an external sealing sheath.Some also have an outer covering on the sheath.There are many ways of laying such as overhead, direct burial, pipeline and underwater.According to the structure, it is divided into symmetrical, coaxial and comprehensive cables.According to the function is divided into field and permanent cable (underground, submarine cable).Communication cable has a wide transmission band and a large communication capacity. It is not easy to be overhauled due to small external interference.Can transmit telephone, telegraph, data and image, etc.(http://www.ccofcn.com/)
