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 cable is damaged. Sometimes it will become the passage of water and moisture, which will cause certain harm to the optical cable; there is no good high flame retardant protective sheath coating

Abstract

The invention relates to the technical field of communication optical cables, in particular to an environment-friendly sheathed optical cable with high polymer and high flame retardancy. Including the sleeve, a number of optical fibers are arranged in the sleeve, fiber paste is arranged between the optical fiber and between the optical fiber and the sleeve, and a strengthening member is also included. The sleeve is arranged in a circle around the strengthening member and wound outside all the sleeves For the binding yarn layer, a water-blocking layer is set between the sleeve and the sleeve, between the sleeve and the reinforcement, and between the sleeve and the binding yarn layer, and an inner sheath and an outer sheath are arranged in sequence outside the binding yarn layer. The invented polymer-modified water-emulsion type asphalt-based thick waterproof coating can effectively resist the shortcomings of low-temperature embrittlement and high-temperature flow after film formation, and has the advantages of high elastic recovery rate, good stability and long storage time.

Description

technical field [0001] The invention relates to the technical field of communication optical cables, in particular to a novel environmentally friendly sheathed optical cable with high polymer and high flame retardancy. 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...
