OUTDOOR OPTICAL FIBER CABLE
Outdoor optical cable is a kind of communication line for optical signal transmission. It is mainly composed of a number of optical fibers in a certain way to form a cable core, which is covered with a sheath, and some are also covered with an outer sheath. The outer cover is thick, with mechanical and environmental characteristics such as pressure resistance, corrosion resistance and tensile resistance. For various applications and environmental conditions, optical fiber cables can be laid overhead, directly buried, duct installation, underwater, indoor and other methods, mainly including central tube armored optical cable, central tube reinforced armored optical cable, stranded armored optical cable, stranded non-metallic fiber cable and stranded non-Figure 8 fiber optic cable.
