Problems solved by technology

Generally, fiber optic cables need to be put into fiber grease and cable grease in order to block water, but fiber grease and cable grease will pollute the environment when they are connected.
Therefore, the improved all-dry optical cable is to put water-blocking yarn when it is in contact with the optical fiber, and put water-blocking tape when making the sheath, but there are also chemical substances in the water-blocking yarn and water-blocking tape, which will also have a certain impact on the environment. pollution

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, the fully dry non-metallic optical cable of the present invention includes a waterproof optical fiber 1 , a loose tube 2 , an FRP central strength member 3 , an inner sheath 4 , an aramid yarn 5 and an outer sheath 6 . Waterproof optical fiber 1 uses a coloring machine to coat a layer of liquid nylon on the outside of the existing 230μm optical fiber. The liquid nylon is made of modified PA11 produced by Polymei Plastic Technology Co., Ltd. The pressure of the coloring machine for the waterproof layer material is 0.4bar~1.0bar. Production The speed is 500-800m / min, and finally infrared heat curing (using the heat generated by the UV lamp to cure the waterproof material). The inner sheath 4 is provided with an FRP central reinforcement 3 and a plurality of loose tubes 2 . Each loose tube 2 is provided with a plurality of waterproof ...

Abstract

The invention discloses a full-dry nonmetal optical cable in which waterproof substances are not filled. Particularly, a waterproof optical fiber is formed by coating the periphery of the optical fiber inside the optical cable with a waterproof layer, wherein the thickness of the waterproof layer is 10-50 micrometers. According to the optical cable, the environment cannot be polluted during the production and use of the optical cable, an environment-friendly effect is achieved, and meanwhile, the waterproof performance of the optical cable can be guaranteed.

Description

technical field [0001] The invention specifically relates to a fully dry non-metallic optical cable. Background technique [0002] Fully dry optical cable is a kind of optical cable that does not pollute the environment. Today, when people are more and more aware of environmental protection, fully dry optical cable has a good prospect. Generally, optical fiber cables need to be put into fiber grease and cable grease in order to block water, but fiber grease and cable grease will pollute the environment when they are connected. Therefore, the improved all-dry optical cable is to put water-blocking yarn when it is in contact with the optical fiber, and put water-blocking tape when making the sheath, but there are also chemical substances in the water-blocking yarn and water-blocking tape, which will also have a certain impact on the environment. pollution. Contents of the invention [0003] The object of the present invention is to solve the defects in the prior art and pr...
