Embodiment 1

[0023] A high-strength light-weight wear-resistant communication optical cable, such as figure 1 As shown, it includes several cable core assemblies 1, the outside of the cable core assembly 1 is provided with a central sleeve 2, the cable core assembly 1 includes a cable core 11 and a sheath 12 sleeved and fixed on the outside of the cable core, the central sleeve 2 The outer casing is provided with a reinforcing tube 3, and the inner surface of the side wall of the reinforcing tube 3 is evenly distributed with a number of reinforcing bars 31 at an equal angle. There is a gap with the central sleeve 2, which can reduce the weight of the optical cable while improving the strength of the optical cable;

[0024] A layer of high-strength elastic sleeve is provided on the peripheral fastening sleeve of the reinforcing tube 3;

[0025] The sheath 12 and the central sleeve 2 are made of one of polyphenylene ether material, polyphenylene sulfide material and polyarylate material;

...

Embodiment 2

[0034] The structure of the communication optical cable is the same as that of Example 1, and the preparation process of the rubber slurry is different; wherein the preparation process of the rubber slurry is: add 10 kg of bromobutyl rubber to 45 kg of chloroform, heat up to 70 ° C and stir to dissolve, and then add 0.5kg of crosslinking agent, 0.7kg of accelerator, 0.08kg of sulfur, 0.7kg of zinc oxide and 3.4kg of carbon black were added therein, and the rubber slurry was obtained after stirring and mixing evenly.

Abstract

The invention discloses a high-strength lightweight wear-resistant communication optical cable comprising a plurality of cable core assemblies. The outer side of the cable core assemblies is providedwith a central sleeve. Each cable core assembly comprises a cable core and a sheath sleeving the outer side of the cable core. The outer side of the central sleeve is sleeved with a reinforcing tube.A plurality of reinforcing strips are uniformly distributed on the inner surface of the side wall of the reinforcing tube and are pressed tightly against the outer surface of the side wall of the central sleeve. The peripheral side of reinforcing tube is sleeved with a high-strength elastic sleeve. The outer side of the cable cores of the optical cable is directly wrapped in the sheath, the outerside of the sheath is wrapped in the central sleeve, the reinforcing tube is pressed tightly against the outer surface of the central sleeve, and the outer side of the reinforcing tube is sleeved withthe high-strength elastic sleeve. The protection by the sheath, the central sleeve, the reinforcing tube and the high-strength elastic sleeve can improve the protection ability of the cable cores andprevent the cable cores from being broken during use or being bitten by a mouse biting the outer sheath.

Description

technical field [0001] The invention belongs to the field of optical cables and relates to a high-strength, light-weight, wear-resistant communication optical cable. Background technique [0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. The optical cable is mainly composed of optical fiber, plastic protective sleeve and plastic sheath. There is no metal such as gold, silver, copper and aluminum in the optical cable, and generally has no recycling value. An optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way, and is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. That is: a cable formed by optical fibers through a certain process...
