Background

With the continuous development and construction of 5G networks, the miniaturization trend of 5G base stations is increasingly detailed, and under the conditions of increasing the number of devices and reducing the space of the devices, the PE (polyethylene) material sheathed optical cable gradually floats out of the water surface in order to meet different environmental requirements and provide more severe requirements for the high temperature resistance and the wear resistance of the optical cable. However, because the PE material retracts too much in the processing process, when the conventional outdoor optical cable retracts to support the sheath, the conventional outdoor optical cable is relieved by respectively embedding a steel wire in the sheath at symmetrical positions, but the optical cable cannot be bent in the direction corresponding to the steel wire, and the laying performance is influenced; and the indoor optical cable is not provided with a component which can sufficiently offset the shrinkage of the sheath, so that the PE sheath cannot be applied and popularized indoors.

SUMMERY OF THE UTILITY MODEL

The utility model discloses return to the PE material sheath course of working and contract too big, and conventional outdoor optical cable influences its performance of laying easily when using the steel wire to do the supporting material, can't the problem of application promotion in indoor, provides a novel FRP inlays type pipeline optical cable, utilizes the rigidity of FRP pipe to support the problem of returning in the PE sheath course of working, and the long distance is worn fine use in the pipeline to the fully provided optical cable.

In order to solve the technical problem, the utility model discloses a following technical scheme: the utility model provides a novel FRP inlays type pipeline optical cable, includes tight tube optic fibre, the outside cover of tight tube optic fibre is equipped with the inner sheath, and the outside cover of inner sheath is equipped with the oversheath, be equipped with two piece at least FRP pipe between inner sheath and the oversheath.

The FRP pipes are arranged in a twisted mode.

The number of the FRP pipes is 6, and the FRP pipes are uniformly distributed between the inner sheath and the outer sheath.

The number of tight-buffered optical fibers is at least two, and the inner sheath wraps the outside of the tight-buffered optical fibers.

The tight-buffered optical fiber comprises a cable core, and a protective layer is wrapped outside the cable core.

Be provided with the stiffening element between inner sheath and the oversheath, stiffening element evenly distributed is between the FRP pipe.

The inner sheath and the outer sheath are both tubular structures made of PE materials.

By adopting the structure, the FRP pipe is arranged between the inner sheath and the outer sheath, the rigidity of the FRP pipe is utilized to support the retraction problem in the processing process of the PE sheath, and the attenuation stability of the optical cable in the temperature range of-40 to 85 ℃ is ensured; through twisting the FRP pipe mutually and setting up, utilize the transposition pitch to compensate when the optical cable is crooked because the different length difference that produce of different position FRP pipe bending radius satisfies that 360 all directions of optical cable all can be crooked at will, and fully satisfies the optical cable and wear fine use in pipeline long distance.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in fig. 1, the utility model provides a novel FRP inlays type pipeline optical cable, including tight cover optic fibre 1, the outside cover of tight cover optic fibre 1 is equipped with inner sheath 2, and the outside cover of inner sheath 2 is equipped with oversheath 3, and is provided with reinforcing element 5 between inner sheath 2 and the oversheath 3, inner sheath 2, oversheath 3 and reinforcing element 5 all are used for protecting tight cover optic fibre 1 to provide the mechanical strength who holds the cable, lays, stores, transports and operation requirement, can prevent that the invasion of moisture and water and the erosion of environment, chemistry and organism from gnawing and stinging etc. and further alleviated the degree of returning in inner sheath 2 and the 3 course of working, support inner sheath 2 and oversheath 3 well, improve and improved the application property of optical cable.
