  • What materials are best for optical cable sheathing

    What materials are best for optical cable sheathing

    The outer sheath of the optical fiber cable is divided into different material types., LSZH, Plenum, Riser . 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, and long-term service conditions. Understand the Environmental. Whether you are designing and manufacturing a new cable or simply choosing an existing one for data, power, fiber optics, or industrial automation, the outer sheath (jacket) is much more than just a speaking cover to the eye; it is, in fact, an important job holder in mechanical protection. The main function of the fiber cable outer sheath is to protect the optical fibers in the optical cable from external damage. But, these do not cover all materials used for fiber optic cables jacketing and there are other plastic materials in addition to these below indicated ones.
