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.
Because the application range of the optical cable is wider, the optical cable needs to be buried under the ground under the general condition, so that the optical cable is stressed for a long time and can be corroded by underground water. The existing optical cable is weak in strength, and long-term stress can possibly cause cracking of the outer coating of the optical cable, so that underground water enters the optical cable, and the optical cable cannot work normally. Accordingly, there is a need for improvements over existing fiber optic cables.
