The differences between communication cable and optical fiber cable
The differences between communication cable and optical fiber cable
The core of optical fiber cable is a communication line which is composited of a certain number of optical fibers in a certain way, with outer jacket and outer sheath, for effecting optical signal transmission. Optical fiber cable has a larger transmission capacity than copper cable, long-distance relay, small size, light weight, no electromagnetic interference. Since 1976, optical fiber cable has developed into the main wire transmission line for long haul line, the city relay, coastal and transoceanic submarine communications, LAN, as well as private network. And begin to spread to areas of city subscriber loop distribution network, provide a transmission line for FTTH and B-ISDN.

Communication cable is usually made of a few or several groups of wires [each at least two] twisted together like rope cable, insulated from each other between each group wire, and often twisted around a center, there is the whole package outside highly insulating cover layer, especially a submarine cable.
Firstly: different material. Communication cable uses metal (mostly copper or aluminum) as conductor; optical firber cable uses glassy fiber as conductor.
Secondly: different transmission signals. Communication cable transmission is electrical signal. Optical fiber cable transmission is optical signal.
Thirdly: different applications. Communication cable is used for energy transmission and low-end data transmission (eg. telephone). Optical fiber cable is used for data transmission.
