So far there are 6 types of sheathing for fibre optic cables, these are PE (Polyethylene), LSZH (Zero halogen compound), PVC (Polyvinyl chloride), PUR (Polyurethane), PA (Polyamide), NBR (Nitrile rubber formulated with PVC), ETFE (Ethylene tetrafluoroethylene). 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. When individual fibers break, light transmission and uniformity. In FTTH and FTTx networks, cable sheath material is often treated as a secondary specification. In reality, cable sheath selection has. How to Choose the Best Suitable MPO Cable sheath? The main differences in the materials and structures of these four types of fiber optic cable sheaths are their flame retardant rating, application scenarios, safety, and physical defense capabilities.
