Abstract
The invention discloses a communication line capable of reducing the stress of optical fibers in a use process. The communication line includes a first coating layer and cable bunches wrapped in the first coating layer; the cross section of the first coating layer is kidney-shaped; a plurality of cable bunches exist and are arranged in parallel; and each cable bunch includes a second coating layer, a middle layer and an optical fiber which are distributed from outside to inside. With the communication line of the invention adopted, stress which is generated by fasteners and is applied to the optical fibers can be avoided, and the communication ability of the optical fibers can be benefitted.
Description
Technical field
The present invention relates to a kind of communication cable structure, particularly relate to and a kind ofly reduce the in use stressed connection of optical fiber.
Background technology
Light transmitting fiber, is called for short optical fiber, the light conduction instrument of the total reflection principle transmission in the fiber that to be a kind of light make at glass or plastics.Fine fibre-optic package, in plastic sheath, makes it to bend and is unlikely to fracture.The transmitter of one end of usual optical fiber uses light emitting diode or beam of laser that light pulse is sent to optical fiber, and the receiving equipment of the other end of optical fiber uses photosensitive components to detect pulse.The cable comprising optical fiber is called optical cable.Because light is more much lower in the loss of electric wire conduction than electricity in fibre-optic transmission loss, more because main production raw material is silicon, reserves are very big, more easily exploit, so low price, impel optical fiber to be used as the media of information of long distance.Along with further optimization or the development in optic fibre manufacture process field and manufacturing equipment field, existing fiber price reduces further, and optical fiber improves rapidly at the total proportion of signal and communication cable.
How rounded cable cross-section of the prior art is, optical fiber is generally arranged on the axis of optical cable, like this when the layout of optical cable, securing member needs to produce enough clamping forces to optical cable and in use produces twisting to avoid optical cable, but above clamping force is unfavorable for the communication performance of optical fiber.
Summary of the invention
How rounded for above-mentioned cable cross-section of the prior art, optical fiber is generally arranged on the axis of optical cable, like this when the layout of optical cable, securing member needs to produce enough clamping forces to optical cable and in use produces twisting to avoid optical cable, but above clamping force is unfavorable for the problem of the communication performance of optical fiber, the invention provides and a kind ofly reduce the in use stressed connection of optical fiber.
For the problems referred to above, a kind of in use stressed connection of optical fiber that reduces provided by the invention solves problem by following technical essential: a kind ofly reduce the in use stressed connection of optical fiber, comprise the first clad and be wrapped in the cable bundle in the first clad, the cross section of described first clad is kidney-shaped, described cable bundle is many, and be arranged in parallel between cable bundle;
Described cable bundle comprises the second clad from outside to inside, middle layer and optical fiber.
Concrete, first clad is as top layer of the present invention, the securing member that structure in kidney-shaped is convenient to adopt pickup groove inwall and waist type construction profile to fit completes the present invention's fixing in laid processes, on above securing member, pickup groove only need be fitted with surface of the present invention, just can be good at preventing the present invention from rolling under external force, being convenient to realization like this avoids securing member to produce compressive stress to optical fiber, is conducive to the ability to communicate of optical fiber.
For improving ability and the humidity-proof ability of each cable bundle external force resistance, described middle layer comprises moisture barrier, strength layer and cushion.
As a kind of structure, simple, the lightweight version of packaging technology, described moisture barrier and strength layer are Copper Foil pipe, and described cushion is Maranyl.
For improving intensity of the present invention, in described first clad, be also coated with intensity muscle.
For ensure the first clad type quality, avoid bonding between cable bundle and produce influence each other, can even the present invention's version that cable bundle each point is stressed under external force, be also filled with packed layer between described cable bundle.
For the benefit of keep the shape of the first clad, make full use of the parcel space of the first clad, avoid mutually disturbing between cable bundle, described cable bundle is distributed in the first clad.
The present invention has following beneficial effect:
First clad is as top layer of the present invention, the securing member that structure in kidney-shaped is convenient to adopt pickup groove inwall and waist type construction profile to fit completes the present invention's fixing in laid processes, on above securing member, pickup groove only need be fitted with surface of the present invention, just can be good at preventing the present invention from rolling under external force, being convenient to realization like this avoids securing member to produce compressive stress to optical fiber, is conducive to the ability to communicate of optical fiber.
