What is fiber optic cable?
Optical fiber and cable General definition: Components of communications cables manufactured to meet optical, mechanical, or environmental performance specifications that make use of one or more optical fibers placed in a clad sheath as the transmission medium and can be used individually or in groups.Optical cable is mainly composed of optical fiber (shaped like glass hair) and plastic protective sleeve and plastic skin, optical cable without other common copper, aluminum and other metals, no recycling value.Components: the basic structure of the cable is generally composed of cable core, strengthening steel wire, filler and sheath and other parts, according to the actual situation can also be done to increase the waterproof layer, buffer layer, insulating metal wire and other components.
Optical fiber and cable as a new generation of transmission media, compared with copper media, optical fiber in security, reliability and network performance has been greatly improved. In addition, the transmission rate of optical fiber is much higher than that of copper cable, and it supports the maximum connection distance of more than 2 kilometers, the formation of large-scale network is the best choice. The other characteristics of optical fiber and cable are anti-electromagnetic interference, strong confidentiality, fast speed, large transmission capacity, but the price is more expensive, in addition, if the use of optical fiber also need to increase the optical transceiver and other equipment, so the cost of investment is larger, the general family occasions relatively less use.
