The inside of the fiber optic cable is covered with a reflective material, or cladding. When light signals hit this material, it reflects off of the walls and travels down the length of the fiber. A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry. 03%, according to the different surface treatment can be divided into galvanized steel wire and phosphating steel wire. This advanced cabling solution allows fast, secure data transfer and telecom over long distances.
