The main function of the fiber cable outer sheath is to protect the optical fibers in the optical cable from external damage. At the same time, it must have. Sheathing has three core values for use in fiber optic design: Protect the fiber. Keep ambient or stray light from creating signal noise (for sensor applications). When individual fibers break, light transmission and uniformity. fiber optic cable in general by the optical fiber core and cladding, coating, strengthening element, an outer sheath, outer sheath as protective layer of cables, such as fire prevention, moistureproof effect, when a fire starts in the data center had important effect on the performance of the outer. The cable sheath is the outer protective layer of a fiber optic cable. Instead of electrical signals traveling through copper wires, digital data is encoded onto light waves that travel through thin strands of glass or plastic. This method allows for significantly higher.
