The OPGW optical cable includes optical fiber and cable sections suitable for long distance power transmission and communications. When the long-distance OPGW optical cable is erected, the two sections of OPGW optical cables are welded at corresponding positions through a welding means, and long-distance power transmission and communication are achieved. As the number of optical fiber cores of the OPGW optical cable increases and the number of external devices increases, the frequency of short-distance use of optical fibers increases. For example, to access a short-distance device at a certain location of a long-distance OPGW optical cable, the OPGW optical cable needs to be disconnected. The construction process is not only heavy in workload, but also affects normal power supply and communication. It is therefore desirable to divide the optical fiber within the OPGW cable into two parts, one part as long-haul communication fiber and one part as spare for accessing short-haul communication equipment.

But a portion of the optical fiber as a spare is not conducted when it is not accessed to the short-range communication device, resulting in a decrease in the total capacity of the optical cable to transmit data.
