Communication cables and fiber optic cables
Wire and cable products for the transmission of audio and various telecommunication information above audio, including local telephone cables, long-distance symmetrical communication cables, coaxial communication cables, cables for telephone equipment and various communication lines. Optical fiber cable is a new high-tech product developed this year. It uses quartz and plastic as the base material to transmit information with light. It has the advantages of large capacity, small size and light weight. Since the 1990s, it has gradually replaced long-distance communication. coaxial cable.
