Background

The network cable is a communication line having a cable core formed of a plurality of wires or conductors insulated from each other and a sealing sheath on the outside. And an outer protective layer is also arranged outside the sheath. There are many laying modes such as overhead, direct burial, pipeline and water bottom. The cable is divided into symmetrical, coaxial and comprehensive cables according to the structure; it is divided into field operation and permanent cable (underground and submarine cable) according to the function. The communication cable has wider transmission frequency band, larger communication capacity and small external interference, but is not easy to overhaul. The device can transmit telephone, telegraph, data, images and the like, and is mainly used for transmitting audio, analog signals of 150kHZ and below and digital signals of 2048kbit/s and below. Under certain conditions, the device can also be used for transmitting digital signals above 2048 kbit/s. The cable is suitable for overhead or pipeline laying lines in urban, suburban and local areas, and can also be directly buried.
