Description

Full-dry type water-blocking optical cable

Technical Field

The utility model relates to a communication optical cable makes technical field, especially a full dry-type optical cable that blocks water.

Background

With the continuous progress and development of science and technology, people pay more and more attention to the surrounding environmental requirements, the optical cable is the main medium for network information transmission in the current society, but most of the optical cables used at present adopt ointment filled in sleeves of the optical cable, pollution to the environment can be caused in the manufacturing process, and in the later maintenance, the naked hand operation is inconvenient, the hands are easily dirty and sticky, the efficiency is not high, and therefore the technical problems existing at present need to be solved.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to above-mentioned prior art not enough, provide an optical cable blocks water of full-dry type.

In order to solve the technical problem, the utility model discloses the technical scheme who takes is: the utility model provides an optical cable blocks water of full-dry type, includes central reinforcement, light unit and oversheath, the light unit is including several optic fibre and optic fibre pine sleeve pipe, the light unit uses central reinforcement as centre of a circle annular to set up in the outer end, be equipped with the powder of blocking water between light unit and the central reinforcement, the powder of blocking water still fills in the light unit, the outermost of central reinforcement is located to the oversheath.

Preferably, the outer end of the central reinforcing member is further provided with a filling rope.

Preferably, an inner sheath and an armored reinforcing layer are further arranged between the outer sheath and the optical unit, the inner sheath is wrapped on the optical unit, and the armored reinforcing layer is arranged at the outer end of the inner sheath.

Preferably, the number of the light units is 4 or more.

Preferably, the filling rope is provided with 1 or more.

Preferably, the water-blocking powder is a powdery polymer.

The utility model has the advantages that: the utility model discloses rational in infrastructure, production and processing is simple and convenient, adopt the powder of hindering water to fill in the optical cable, have good hydroscopicity, prevent that inside from being affected with damp impaired, and can not pollute all ring edge borders, and when later maintenance, reduced the oleamen to optical fiber splice's influence, reduce the butt fusion loss of joint, can not make dirty hand, the naked hand operation of being convenient for can not make dirty; paste when maintaining, have more quick maintenance efficiency, good dampproofing protection, better environmental protection.

10. A central reinforcement; 20. a light unit; 21. an optical fiber; 22. an optical fiber loose tube; 30. an outer sheath; 40. water-blocking powder; 50. filling a rope; 60. an inner sheath; 70. and an armored reinforcing layer.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, a full-dry type water-blocking optical cable includes a central reinforcement 10, an optical unit 20 and an outer sheath, wherein the optical unit 20 includes a plurality of optical fibers 21 and an optical fiber loose tube 22, the optical unit 20 is annularly disposed at an outer end with the central reinforcement 10 as a circle center, and the optical unit 20 is provided with 4 or more optical fibers surrounding the central reinforcement 10, and water-blocking powder 40 is disposed between the optical unit 20 and the central reinforcement 10, so that the water-blocking powder 40 can effectively absorb water and prevent moisture, and the water-blocking powder 40 is further filled in the optical unit 20, thereby effectively protecting the optical fibers 21 from being damaged by moisture, the outer sheath 30 is disposed at an outermost layer of the central reinforcement 10, and the inner optical unit 20 and the central reinforcement 10 are effectively protected from being damaged by the outer sheath 30.

Wherein, the outer end of the central reinforcing member 10 is further provided with a filling rope 50, and the tensile resistance and the swing resistance of the optical cable can be improved through the filling rope 50.

Wherein, the used filling ropes 50 are provided with 1 or more, so that the tensile resistance and the swing resistance of the optical cable are stronger.

Wherein, still be equipped with inner sheath 60 and armor enhancement layer 70 between outer sheath 30 and optical unit 20, through wrapping up inner sheath 60 in optical unit 20, protection optical unit 20 that can be fine to still locate the outer end of inner sheath 60 with armor enhancement layer 70, the inside optical unit 20 of protection that can be better prevents that inside optical unit 20 from being damaged the rupture.

Wherein, the water-blocking powder 40 is powdery polymer and has good water absorption effect and moisture resistance.

The above embodiments are merely illustrative and not restrictive, and all equivalent changes and modifications made by the methods described in the claims are intended to be included within the scope of the present invention.
