Communication cables refer to cables used for close range audio communication and long-distance high-frequency carrier and digital communication and signal transmission, and are one of the five major cable products in China. According to the purpose and scope of use of communication cables, they can be divided into six series of products, namely, urban communication cables (including paper insulated local telephone cables, polyolefin insulated polyolefin sheathed local telephone cables), long-distance symmetrical cables (including paper insulated high and low frequency long-distance symmetrical cables, copper core foam polyethylene high and low frequency long-distance symmetrical cables and digital transmission long-distance symmetrical cables), coaxial cables (including small coaxial cables, medium and small coaxial cables), submarine cables (including symmetrical submarine and coaxial submarine cables), optical fiber cables (including traditional cable type, ribbon array type and skeleton type), and RF cables (including symmetrical RF and coaxial RF).
Communication cable production factories are distributed throughout the country. In addition to producing long-distance communication cables and local telephone cables, China has also made significant progress in the production of fiber optic cables and polyolefin insulated and fully plastic local telephone cables. Many domestic manufacturers and research institutions have introduced technology and equipment from abroad to begin production. Every year, a small amount of polyolefin insulated polyolefin sheathed all plastic local telephone cables are sold to Hong Kong, Macao, Southeast Asia, and the Middle East in China.
