The outer sheath of the optical fiber cable is divided into different material types., LSZH, Plenum, Riser . What Is a Cable Sheath and Why It Matters 🔍 The cable sheath is the outer protective layer of a fiber optic cable. Its primary functions include: While the optical fiber itself remains largely unchanged, the sheath material determines how the cable behaves in fire scenarios, outdoor environments. The main function of the fiber cable outer sheath is to protect the optical fibers in the optical cable from external damage. As the protective layer of the cable, the outer sheath has the functions of fire prevention and moisture resistance, which has an important impact on the performance of the. Fiber optic cables are generally composed of fiber optic cores, cladding, coatings, reinforced components, and outer sheaths. Keep ambient or stray light from creating signal noise (for sensor applications).
