Abstract

The invention discloses a communication cable which comprises a nylon rope, a non-woven fabric layer, a plastic framework, and optical fibers. The non-woven fabric layer is wound outside the nylon rope. The plastic framework is arranged outside the non-woven fabric layer. The outer side of the plastic framework is provided with bulges, which are distributed in a circular array. Each optical fiber is arranged between two bulges. A loose tube is arranged outside each optical fiber. A glass fiber layer, a shielding layer and a steel pipe are arranged outside the plastic framework, and the glass fiber layer, the shielding layer and the steel tube are arranged in sequence from inside to outside. The two ends of the shielding layer are provided with clamping parts, which are in clamped connection with the steel pipe. The communication cable has the advantages of high intensity, good stability, and long service life.

Description

technical field [0001] The invention relates to a communication cable. Background technique [0002] Through-wire cables are cables for the transmission of telephone, telegraph, fax documents, television and radio programmes, data and other electrical signals. It consists of more than one pair of mutually insulated wires twisted together. Compared with overhead open wires, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and less affected by natural conditions and external interference. [0003] A cable core is composed of a plurality of mutually insulated wires or conductors, and a communication line with a sealed 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 its ...
