Abstract

The invention discloses a manufacturing method of a small-sized multi-core full-dry-type introduced optical cable. The small-sized multi-core full-dry-type introduced optical cable comprises an outer sheath and an inner sheath, wherein aramid fibers are arranged on the inner side wall and the outer side wall of the inner sheath respectively, and multi-core micro-beam tubes are arranged in the inner sheath, and are arranged among the aramid fibers. The manufacturing method of the small-sized multi-core full-dry-type introduced optical cable comprises the steps that (1) a layer of aramid fibers is added to the positions among the multi-core micro-beam tubes in a reinforced mode, a rip cord is embedded into the aramid fibers in a parallel mode, (2) the inner sheath is arranged at the periphery of the multi-core micro-beam tubes in a pressing wrapping mode, (3) a layer of aramid fibers is added to the periphery of the inner sheath in a reinforced mode, a rip cord is embedded into the aramid fibers of the step (3) in a parallel mode, and (4) the outer sheath is arranged at the periphery of the aramid fibers of the step (3) in a pressing wrapping mode, and two pieces of resin fiber reinforced plastic are embedded into the outer sheath in a parallel mode. The manufacturing method of the small-sized multi-core full-dry-type introduced optical cable is simple; due to the fact that double sheaths are adopted, the mechanical property of the small-sized multi-core full-dry-type introduced optical cable is effectively ensured; due to the fact that the mode that the multi-core micro-beam tubes are used for protecting optical fibers, and water resistance yarn is used for resisting water is adopted, permeation and diffusion of moisture are effectively prevented, and reliability of an optical cable line is improved.

Description

technical field [0001] The invention relates to an optical cable and a manufacturing method thereof, in particular to a miniaturized multi-core fully dry drop optical cable and a manufacturing method thereof. Background technique [0002] With the development of optical communication, more and more optical cables are used in optical transmission networks, which provides convenience for more efficient signal transmission. But at the same time, with the increase in the amount of optical cable laying, the available space in the area is gradually decreasing. In the future, optical cables that can adapt to various application environments will be favored by various users. It adopts micro-bundle tube and fully dry water-blocking structure. The use of micro-bundle tubes can reduce the volume of optical cables, reduce the weight of optical cables, reduce the difficulty of laying and maintenance of optical cables, and reduce construction costs. At the same time, it can increase the ...
