An environment-friendly water-based nano anti-aging coated optical cable

Abstract

The invention relates to the technical field of communication optical cables, in particular to an environment-friendly water-based nanometer anti-aging coated optical cable, which includes a sleeve, a number of optical fibers are arranged in the sleeve, fiber paste is arranged between the optical fiber and the optical fiber, and between the optical fiber and the sleeve. Including reinforcements, the sleeves are arranged in a circular pattern around the reinforcements, wrapping yarn layers around all sleeves, between sleeves, between sleeves and reinforcements, between sleeves and yarn binding layers A water-blocking layer is set, and an inner sheath and an outer sheath are arranged in sequence outside the yarn-binding layer. It has low cost, less pollution, less harm to the human body, good abrasion resistance, and strong anti-aging ability.

Description

technical field [0001] The invention relates to the technical field of communication optical cables, in particular to a novel waterproof coated optical cable. Background technique [0002] With the growth of information and the popularization of the network, as an effective means of large-capacity and long-distance transmission, optical cables have been widely used. The optical cable structure in the communication field is roughly divided into three types: layer twisted optical cable, central beam tube optical cable and skeleton optical cable. [0003] Layer twisted optical cable is to add the colored optical fiber and fiber paste into the sleeve at the same time, the optical fiber is movable in the sleeve, and different sleeves are stranded along the strength member to form a cable core, and a sheath is set outside the cable core to obtain a layer twisted fiber optic cable. The main features of the layer-stranded optical cable are: the strengthening member is located in t...

Problems solved by technology

[0006] Although the above-mentioned patents can improve the performance of the twisted cable, after a period of use, the fiber paste in the sleeve will become less and less due to environmental changes, and the reduction of the fiber paste will cause some voids to appear inside. These voids are damaged when the optical cable is damaged. Sometimes it will become a path of water and moisture, which will cause certain harm to the optical cable; there is no good anti-aging coating optical cable protective coating
