Description of GJX (F) H fiber, bow type drop cable for network access In GJX (F) H fiber bow type drop cables for network access, the optical unit is located at the center, and placed around two parallel nonmetal strength members (FRP or KFRP) or metal strength members. An extruded black or chromatic polyvinyl chloride (PVC) or low-smoke halogen-free material (low-smoke, halogen-free, flame retardant) acts as the sheath.

Features The simple structure and light weight ensure its strong practicability. This optical fiber is designed with a unique groove, making it easy to strip or connect the fiber. This designs simplifies installation and maintenance operations for the fiber. This product belongs to special low-bend-sensitivity fiber, which will provide a larger bandwidth in order to reinforce the performance of network transmission. The two parallel FRP or metal strength members offer an excellent compression resistance to the optical cable and will easily protect the optical fiber. We use an environmentally friendly, low-smoke halogen-free flame-retardant polyethylene or flame retardant polyvinyl chloride as the optical fiber sheathe. This optical fiber is suitable for various connectors and can be used to connect the end of the optical fiber with other connectors.
