What kind of plastic is best for fiber optic cable sheathing

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. However, the PVC sheathed optical cable will produce dense smoke when. 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. One important component is the outer jacket of the cable. Outer jackets can be made from a number of materials, and generally speaking, the jacket materials can work with any fiber cable type. PVC cable sheathing is popular because of its strong physical properties, like high strength and strong insulating properties. It can resist oils, acids, abrasions, sunlight, and heat.
