Features
The self-supporting optical fiber drop cable is a type of special low-bend-sensitivity fiber that can provide more bandwidth and enhance network transmission performance. The self-supporting optical fiber drop cable uses a single steel wire with additional strength member and has great tensile performance. The self-supporting optical fiber drop cable has characteristics of simple structure, light weight and strong practicability. The self-supporting optical fiber drop cable uses special groove design, so it is easy to peel, connect, install and maintain. The self-supporting optical fiber drop cable uses low smoke zero halogen flame retardant polyolefin, so it is environmentally friendly and safe. The self-supporting optical fiber drop cable can be matched with a variety of field connectors and into point in scene.
