OPGW cable uses all metal materials, which has good mechanical and environmental properties. It’s suitable for high voltage electric lines over 110kv. The cable structures are commonly central tube and stranded types.
The main function of the fiber cable outer sheath is to protect the optical fibers in the optical cable from external damage. Requirements So the material of the fiber optic cable outer sheath must be able to withstand the sun and rain, and not crack due to ultraviolet radiation. At the same time, it must […]
The fire rating of fiber optic cable can be specificed into 3 types, which are OFNP, OFNR and OFN. Before we can talk about the flame retardant grade, we can first understand what is LSZH (Low Smoke Zero Halogen). What Is LSZH As early as the mid-1980s, halogen-containing (especially brominated) flame retardant polymer systems were […]
Optical fiber manufacturing is the process of making optical fibre from silicon tetrachloride and other raw materials. This process of optical fiber manufacturing determines the mechanical strength, transmission characteristics and service life of the optical fiber, which is very important to ensure the quality of the optical fiber and fiber optic cable. Optical Fiber Manufacturing It […]
