It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. Optical cable is mainly composed of optical fiber (glass fiber as thin as hair) and plastic protective casing and plastic outer skin. There is no gold, silver, copper, aluminum or other metals in the optical cable, and it is generally of no recycling value. Optical cable is a communication line in which a certain number of optical fibers are formed into a cable core in a certain way, and some are also covered with an outer sheath to realize the transmission of optical signals, that is: a cable formed by optical fiber (optical transmission carrier) through a certain process. The basic structure of the optical cable is generally composed of several parts such as cable core, reinforcing steel wire, filler and sheath. In addition, there are waterproof layer, buffer layer, insulated metal wire and other components as needed.

[0003] The optical cable is composed of three parts: a reinforcing core and a cable core, a sheath and an outer sheath. The cable core structure includes two types: single-core and multi-core. The single-core type includes two types: a solid type and a bundle type, and the multi-core type includes two types: a ribbon type and a unit type. The outer sheath includes two types: metal armored and non-armored. The optical cable is buried underground, and the land needs to be excavated for maintenance. The existing underground optical cable maintenance and excavation equipment takes a long time to dig, and has low work efficiency.
