What is polyethylene optical cable sheath material

Polyethylene (PE) optical cable sheath material is an outer protective material designed for optical fiber cables, with excellent mechanical strength, weather resistance and insulation properties. As the first line of defense for cables, it can effectively resist external factors such as moisture. Choosing the appropriate outer sheath material for fiber optic cables is crucial for ensuring the cable's durability, protection, and performance under specific environmental conditions. GL FIBER here's a guide to help you choose the right outer sheath material: 1. 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. Flame-retardant optical cable is a flame-retardant polyethylene sheath material instead of ordinary optical cable polyethylene sheath material, so that the optical cable has flame-retardant properties.
