Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1 and Fig. 2, a kind of base station of the present utility model dragging optical cable, comprise some tightly packaged fibers and be coated on sheetmetal layer 3, reinforcement 4 and the oversheath 5 outside tightly packaged fiber successively, wherein:
Every root tightly packaged fiber comprise optical fiber 1 and be coated on hard-pressed bale layer 2 outside optical fiber 1,
Optical fiber 1 adopts bend insensitive optical fiber; Effectively can solve the transmission performance of optical fiber under micro-curved state;
Hard-pressed bale layer 2 comprises resinous coat 21 and hard-pressed bale material 23, and resinous coat 21 is close to and clad optical fiber 1, and resinous coat 21 is provided with point tomography 22 vertically, and hard-pressed bale material 23 adopts nylon, and this hard-pressed bale material 23 is close to and resin-coated coating 21; On the surface of hard-pressed bale material 23, offer tearing port 24, the direction of tearing of tearing port 24 is radial direction, and namely hard-pressed bale material 13 can be torn by tearing port 24, exposes inner resinous coat 21;
Sheetmetal layer 3 adopts ribbon spiral armouring, ensures lateral pressure resistant performance and the tensile property of optical cable with this, and steel-tape armouring can solve lightning-arrest function after being connected with copper cash simultaneously;
Reinforcement 4 is made up of aramid yarn, can improve the tensile property of optical cable;
The external diameter of oversheath 5 is 5.0mm, this oversheath 5 adopts Polyurethane Thermoplastic Elastomer rubber (TPU) to make, this material can deliquescing under certain temperature, and can remain unchanged at normal temperatures, make whole optical cable have stronger outdoor application performance, also meet simultaneously and use in the machine room of base station.
Base station of the present utility model dragging optical cable, traditional tightly packaged fiber structure is reduced to three-decker by tightly packaged fiber wherein, strengthens the degree of packing of optical cable, and arranges tearing port and point tomography respectively on its surface and inside, can so that the stripping of optical fiber.Base station of the present utility model dragging optical cable, has stronger outdoor application performance, also meets simultaneously and uses in the machine room of base station.Optical cable can meet environment temperature-50 ~+100 DEG C, therefore expands the application scenario of optical cable.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when not departing from spirit and scope of the present utility model, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present utility model, should be limited by each claim.
