Abstract

The invention relates to a manufacturing technology of optical cables for a long-distance backbone network and a relay network in a communication optical cable, in particular to a novel all-medium armor optical cable. The optical armor cable comprises a plurality of optical fibers. Beam tubes cover the optical fibers, a plurality of nonmetal round rods are sequentially arrayed around the beam tubes, a nonmetal longitudinal covering band covers the nonmetal round rods, the portion between the nonmetal longitudinal covering band and the beam tubes and the portion between the nonmetal longitudinal covering band and the nonmetal round rods are filled with water blocking layers, and a sheath covers the nonmetal longitudinal covering band. According to the optical cable, the layer-stranding structure is changed into a center tube structure, and all elements in the optical cable are nonmetal; in the production process, stable excess length can be guaranteed, the influence of metal bending on the cable is avoided, and the capacity for protecting the optical fibers is high; in the construction process, shock resistance and flattening resistance are high; in the practical use process, unnecessary lightning stroke accidents can be effectively avoided, and compared with metal media, oxidation resistance and corrosion resistance are high. Through multiple experiments, transmission indexes and environment indexes of the optical cable meet the requirement.

Description

technical field [0001] The invention relates to the manufacturing technology of optical cables for long-distance backbone networks and relay networks in communication optical cables, in particular to a novel all-dielectric armored optical cable. Background technique [0002] At present, most optical cables are strengthened by steel wires in the center and stranded in a certain order to form a cable, and the metal tape is longitudinally wrapped and armored, and then the outer sheath is used, and the steel wire is basically used as the central reinforcement. With longitudinal armored sheath. [0003] With the rapid development of the domestic communication industry in recent years, the scope of optical communication applications has expanded. Optical cables used in long-distance backbone networks and trunk networks play a very important role in the entire optical cable industry. The existing armored optical cables have the following disadvantages in various aspects: the posi...
