PVC is the most widely used fiber optic cable outer sheath material. It has good performances, good chemical resistance and weathering resistance, low cost, low flammability, and can meet the requirements of general occasions. The price of LSZH sheath is relatively high, but due to its environmental friendliness and safety, it is very suitable for indoor. 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. 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.
