In order to improve the capacity of the optical cable to bear the load and resist the axial stress that may be generated in the laying and application of the optical cable, the steel strand as the strengthening part of the optical cable is the most suitable, and has a certain flexibility. Steel. The galvanized steel strands for optical fiber cables are made of high-quality carbon steel wire rods through a series of processes such as heat treatment, peeling, water washing, pickling, water washing, solvent treatment, drying, hot-dip galvanizing, post-treatment, and wire drawing into the. Total internal reflection of light is used in the fiber optical cable. Depending on the amount of power needed and the distance needed, the fibers are designed to allow light to travel in parallel with the optical fiber.
