The optical cable mainly comprises optical fibers (glass filaments like hair), a plastic protective sleeve and a plastic sheath, and metals such as gold, silver, copper aluminum and the like are not contained in the optical cable, so that the optical cable generally has no recycling value. The optical cable is a communication line for realizing optical signal transmission, wherein a certain number of optical fibers form a cable core in a certain mode, a sheath is covered outside the cable core, and an outer protective layer is covered outside the cable core. With the advent of the information age, the transmission amount of information has been increased explosively, and as an effective means for large-capacity and long-distance transmission, optical fiber cables have been widely and largely applied, and the application of optical fiber cables has also gradually been developed from long-distance trunks to metropolitan area networks and access networks.
