Abstract
The invention relates to a pipeline-type butterfly-shape optical cable. The optical cable comprises aramid fiber yarn ropes (1), a sheath layer (5) and a butterfly-shape optical cable unit. The butterfly-shape optical cable unit comprises an optical fiber (6), reinforcement cores (8) and an inner sheath (9). An external portion of the optical fiber (6) is wrapped by the inner sheath (9). A cross section of the inner sheath (9) is a butterfly structure. The two reinforcement cores (8) which are mutually parallel to each other are arranged in the inner sheath (9). And the two reinforcement cores (8) are symmetrical about the optical fiber (6). The aramid fiber yarn ropes (1) which are mutually parallel to each other are arranged on two sides of the inner sheath (9). A waterproof layer (2), a yarn bundling layer (3) and a metal tape layer (4) successively wrap between the inner sheath (9) and the sheath layer (5) from inside to outside. The optical cable of the invention has the advantages that an external diameter of a whole structure is small; weight is light; strong tensile and compression resistance performance are possessed; a full dry type structure is possessed; indoor and outdoor wiring can be achieved.
Description
Technical field
The present invention relates to a kind of dished optical cable, particularly a kind of pipeline type butterfly optical cable.
Background technology
Along with fiber-to-the-home arriving, in the construction of " last kilometer ", traditional selection is nothing more than being in the common pipe type optical cable wiring inlet pipe road, and the sheath that existing butterfly optical cable comprises optical fiber, the cross section that is coated on the optical fiber periphery is butterfly is arranged in the sheath and is positioned at the strengthening core of optical fiber both sides.Wherein, strengthening core is made by metal or nonmetallic materials.The optical fiber easy damaged of existing butterfly optical cable, easily permeated by water, can't satisfy requirements for pipes.
Chinese patent application number: 201220286001.3 disclose a kind of branch butterfly optical cable, comprise two optical cable units and unit connector, two optical cable units connect by the optical cable connector, optical cable unit comprises optical fiber, oversheath and two steel wire reinforcements, two steel wire reinforcements are located in the oversheath, such structure in use, optical fiber is running into external impacts moment, external force acts directly on the optical fiber, cause easily the damage of fibercuts or optical fiber, and optical cable drenched with rain or is being in wet environment, and moisture easily infiltrates into optical cable, causes the communication quality variation.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, the pipeline type butterfly optical cable that a kind of one-piece construction external diameter is little, lightweight and have stronger tension, compressive property is provided, the dry type structure has the dual-purpose advantage of indoor and outdoor wiring.
Purpose of the present invention is achieved through the following technical solutions: a kind of pipeline type butterfly optical cable, it comprises aramid yarn rope, restrictive coating and butterfly optical cable unit, the butterfly optical cable unit comprises optical fiber, strengthening core and inner sheath, the outer wrap of optical fiber has inner sheath, the xsect of inner sheath is butterfly structure, be provided with two strengthening cores that are parallel to each other in the inner sheath, and two strengthening cores are symmetrical about optical fiber, be provided with the aramid yarn rope that is parallel to each other in the both sides of inner sheath, be coated with successively from inside to outside water blocking layer between inner sheath and the restrictive coating, prick layer and strap layer.
Described water blocking layer, bundle layer, strap layer and restrictive coating xsect all are the circular configurations take optical fiber as the center of circle.
The both sides of described inner sheath offer symmetrical groove.
Described water blocking layer is made by the PVC material of band shape.
Described strap layer is steel band or aluminium strip.
Described restrictive coating is outside in strap layer by extrusion moulding.
The present invention has the following advantages:
1, the aramid yarn rope can improve tensile strength, and strap layer can strengthen the humidity resistance of optical cable, and restrictive coating can improve the compressive property of optical cable.
2, the one-piece construction external diameter is little, lightweight, easy for installation.
3, has the dual-purpose advantage of indoor and outdoor wiring.
4, optical cable is finished by stranding and the cooperation of sheath operation of optical cable production, need not increase manufacturing facilities.
