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. Namely: a cable formed by subjecting an optical fiber (optical transmission carrier) to a certain process. The basic structure of the optical cable generally consists of a sheath, a cable core, a filler and other parts, and components such as a waterproof layer, a buffer layer, an insulated metal wire and the like are also arranged according to requirements. However, the traditional optical cable has poor tensile and compressive properties and is not abrasion-resistant, rodents or birds often stay on the suspended part of the optical cable during the use process, and can cause additional tension and pressure on the optical cable, and once the optical fiber inside the optical cable is pulled, the problems of unsmooth communication and even communication interruption can be caused. The present utility model therefore provides a stretch resistant fiber optic cable that effectively solves the above-mentioned problems.
