Background
In the prior art, an outdoor optical cable is generally divided into a layer-stranded type, a central beam tube type and a skeleton type, wherein the layer-stranded type optical cable is formed by stranding a plurality of loose tubes with optical fibers or optical fiber ribbons inside around a central reinforcing member to form a cable core, one or more protective layers are coated outside the cable core, and wrapping yarns are required to be wound on the loose tubes, so that the loose tube structure is stable; the central beam tube type optical cable is formed by putting an optical fiber or an optical fiber ribbon in a loose tube, and coating at least one protective layer outside the loose tube; the skeleton type optical cable is formed by placing optical fibers or optical fiber ribbons in skeleton grooves of a skeleton and then coating at least one protective layer outside the skeleton. In the prior art, a layer-stranded optical cable needs complex stranding equipment, and in the stranding process, loose tubes and internal optical fibers or optical fiber belts can be damaged, and when the temperature changes, the loose tubes can be pricked or pricked due to the fact that the expansion coefficients of the materials of the loose tubes and the wrapping yarns are different; the central beam tube type optical cable needs to peel the whole loose tube, and only needs a part when being actually used in a certain place, so that the influence on the unused part can be caused. Because of the relatively large size of the skeleton, the core density of the skeleton-type optical cable still needs to be improved, and the production of the skeleton requires professional skeleton manufacturing equipment, so that the qualification rate of the rotating skeleton grooves is relatively low.
