Waterproofing type rat-proof radio frequency remote optical cable and manufacturing method of optical cable

Abstract

The invention discloses a waterproofing type rat-proof radio frequency remote optical cable and a manufacturing method of the optical cable. The optical cable comprises an outer protecting layer, wherein waterproofing glass fiber yarns are coated in the outer protecting layer, a plurality of nylon tight wrapping layers are coated in the waterproofing glass fiber yarns, and optical fibers are arranged in each nylon tight wrapping layer. The manufacturing method comprises the following steps that (1) the nylon tight wrapping layers are respectively wrapped at the outer surfaces of a plurality of optical fibers; (2) the outer protecting layer is wound at the periphery of the nylon tight wrapping layers; (3) waterproofing glass fibers are filled between the outer protecting layer and the nylon tight wrapping layers. The optical cable and the manufacturing method have the advantages that the method is simple, the waterproofing glass fiber yarns are adopted, and various properties such as rat biting prevention of the optical cable are added; nylon tight sleeves are adopted, the attenuation has better stability, and meanwhile, the better rat biting prevention performance is also realized.

Description

technical field [0001] The invention relates to an optical cable and a manufacturing method thereof, in particular to a water-blocking mouse-proof radio frequency remote optical cable and a manufacturing method thereof. Background technique [0002] The radio frequency remote optical cable is suitable for the introduction of communication base stations. The main feature of this optical cable is high-strength non-metallic reinforcement to ensure long-term stability of optical fiber transmission performance; small outer diameter, light weight, flame retardant, easy to peel, and high flexibility; Each optical unit can be directly terminated with a standard connector; LSZH flame-retardant material is used to meet the performance requirements of flame retardancy and environmental protection; it is convenient for construction and maintenance. With the great development of FTTx construction in recent years, optical fibers are gradually moving closer to the user end, and FTTx constr...

Problems solved by technology

The traditional water-blocking indoor and outdoor dual-purpose radio frequency remote optical cable generally adopts water-blocking aramid yarn reinforcement structure and does not have the anti-rat bite function, such as figure 1 As shown, aramid yarn reinforcements are widely used in indoor optical cables. Aramid yarn is a synthetic fiber with excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. However, aramid yarn High cost in use, especially for water-blocking aramid yarns
