Abstract
The utility model relates to a communication optical cable, especially relates to a butterfly-shaped indoor incoming optical cable comprising an outer sheath, an optical fiber, and a reinforced member parallel to the optical fiber. The optical fiber and the reinforced member can be wrapped by the outer sheath, which is wrapped by a solid lubricating layer. The butterfly-shaped indoor incoming optical cable provided with the solid lubricating layer has a small friction coefficient, is convenient to install in a common pipeline, is suitable for the pushing-in installation method, and can be used to reduce the laying costs of the optical cable. The organosilicone plastics adopted by the solid lubricating layer and the low smoke zero halogen adopted by the outer sheath are innocuous and non-poisonous to human bodies, therefore the butterfly-shaped indoor incoming optical cable is suitable for being used as the indoor incoming optical cable.
Description
Technical field
The utility model relates to a kind of communications optical cable, especially the butterfly indoor leading-in optical cable.
Background technology
Existing most of multitenant unit does not all have the pipe special of laying optical cable, carries out fiber cable laying and adopt cement pipe, PE to mould pipe or PVC plastic tube etc., and the inwall friction factor of this type of pipeline is very large, it is low to lay efficient.And the difficulty of setting up optical cable usefulness pipeline has also been strengthened in expensive building cost and limited space.The butterfly indoor leading-in optical cable of prior art mainly adopts GJX (D) FH structure, and version is: optical fiber (band)+reinforcement+oversheath.In use there is following shortcoming in the butterfly indoor leading-in optical cable of prior art: 1) friction factor is large, is not easy to install in pipeline commonly used; 2) Method for Installation is pulled out in employing usually, so that the laid down cost of optical cable is high.
Summary of the invention
The purpose of this utility model is to overcome shortcoming and defect of the prior art, provides a kind of friction factor little butterfly indoor leading-in optical cable.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: the butterfly indoor leading-in optical cable, comprise oversheath, optical fiber, the reinforcement parallel with optical fiber, and oversheath parcel optical fiber and reinforcement also comprise the solid lubricant layer that wraps up oversheath.
Wherein, described solid lubricant layer is the silicone plasties layer.
Wherein, the thickness of described solid lubricant layer is 0.3-0.5mm.
Wherein, the cross section of described solid lubricant layer is rectangle or round rectangle.
Wherein, described optical fiber is arranged at the center of the inside of oversheath.
Wherein, described reinforcement is two, and is symmetricly set on the inside of oversheath centered by described optical fiber.
Wherein, the middle part of the both sides of described oversheath is respectively arranged with the groove of V-arrangement.
Wherein, described optical fiber is at least two, described at least two optical fiber composition fibre ribbon that is fixed together.
Wherein, described oversheath is the low-smoke non-halogen flame-retardant oversheath.
The utility model has the advantages that:
Butterfly leading in cable friction factor with solid lubricant layer is little, is convenient to install in pipeline commonly used, and is applicable to push Method for Installation, has reduced the laid down cost of optical cable; The halogen-free low-smoke flame retardant material that the silicone plasties that solid lubricant layer adopts and oversheath adopt is all nontoxic to human body, and therefore, butterfly leading in cable of the present utility model is suitable as indoor leading-in optical cable.

Fig. 2 is the cross section view of the utility model embodiment two.
Comprise among Fig. 1 and Fig. 2:
Optical fiber-1; Reinforcement-2; Oversheath-3; Solid lubricant layer-4; Groove-5; Fibre ribbon-6.
Embodiment
Understanding for the ease of those skilled in the art is described in detail the utility model below in conjunction with accompanying drawing.
Embodiment one:
With reference to figure 1, butterfly indoor leading-in optical cable of the present utility model comprises oversheath 3, optical fiber 1, the reinforcement 2 parallel with optical fiber 1, and oversheath 3 parcel optical fiber 1 and reinforcements 2 also comprise the solid lubricant layer 4 that wraps up oversheath 3.
The cross section of solid lubricant layer 4 is rectangle or round rectangle.For improving the stability of optical cable signal transmission, optical fiber 1 is arranged at the center of the inside of oversheath 3.
In the present embodiment, two reinforcements 2 are arranged at respectively the upper and lower of oversheath 3 and parallel with optical fiber 1, and centered by optical fiber 1 symmetrically.The middle part of the left and right sides of oversheath 3 is provided with the groove 5 of V-arrangement.The present embodiment " on " orientation such as D score " left side " " right side ", take Fig. 1 as reference direction.Reinforcement 2 can be protected optical fiber 1 better, and the simultaneously design of the groove 5 of V-arrangement conveniently continues so that optical cable is easily peeled off, and simplifies installation and maintenance.
Oversheath 3 is low-smoke non-halogen flame-retardant oversheath 3.As entering the house type optical cable, need employing nontoxic to human body, the material of environmentally safe, the oversheath 3 and the silicone plasties making solid lubricant layer 4 that adopt halogen-free low-smoke flame retardant material to make satisfy the user to the demand for security of indoor leading-in optical cable.
Embodiment two:
With reference to figure 2, embodiment two is with the difference part of embodiment one: optical fiber 1 is at least two, and described at least two optical fiber 1 form fibre ribbon 6.The design of fibre ribbon 6 can increase transmission capacity, satisfies different users's demand, and applicability is wider.The further feature of embodiment two is identical with embodiment one, no longer gives unnecessary details at this.
Primary structure of the present utility model is: optical fiber 1(band)+and reinforcement 2+ oversheath 3+ solid lubricant layer 4.Technological process is: 1 painted (also being with after the painted) → reinforcement 2+ oversheath 3 → solid lubricant layer 4 → optical cable outbound of optical fiber 1 warehouse-in → optical fiber.
The utility model takes into full account that people have designed the butterfly indoor leading-in optical cable with solid lubricant layer to the demand of indoor leading-in optical cable under the existing living environment.Reduce the fiber cable laying cost, improved the applicability of optical cable.Guarantee again simultaneously optical property, the mechanical property of optical fiber.Technique is simple, and market outlook are boundless.
Above content only is preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
