What is the communication cable

Communication Cable Communication Optical Fiber Cable. Communication cable is that a number of the root (core) fiber (typically from a few to thousands of core-core) constitutes the heart and the outer cable sheath formed. Fiber and traditional copper coaxial symmetrical copper loop and loop compared to its transmission capacity is much greater; attenuation less; long distance transmission; small; light weight; no electromagnetic interference; low cost, is the most promising communication transmission media. It is widely used in telecommunications, electricity, radio ---- so the signal transmission of various departments, will gradually become the main communications network. Fiber cable in the structure and the main difference is that cable must have stiffeners to withstand external mechanical load, in order to protect the fiber from a variety of external mechanical effects.
