Description
Technical field
This utility model belongs to technical field of optical fiber, is specifically related to a kind of optical fiber sheath.
Background technology
Along with developing rapidly of data communication industry, the carrier that optical fiber transmits as data is just widely adopted.Optical fiber
Laying form be buried and built on stilts, and along with the transformation of city netting twine, major part goes underground.In order to prevent the light of underground
Fine, optical cable is arisen at the historic moment by the protective cover material of insect bite or corrosion, optical fiber and optical cable.Optical fiber, protecting sleeve of optical cable mainly use at present
Polyolefin, has light weight, bending strength is big, coefficient of friction is little, good seal performance, the feature such as corrosion-resistant, existing optical fiber jacket
Easily bending, optical fiber bends the most therewith, therefore adds the bending loss of optical fiber, has had a strong impact on the communication quality of optical fiber.
Utility model content
The purpose of this utility model is to provide a kind of optical fiber sheath, with asking of solving to propose in above-mentioned background technology
Topic.
For achieving the above object, this utility model following technical scheme of offer: a kind of optical fiber sheath, including optical fiber, light

Jacket layer 6, four positions of the up, down, left and right of described external sheath layer 6 are respectively provided with one and strengthen steel wire 7.
Operation principle: optical fiber is inserted in the Loose tube layer 3 that high-modulus is made, fills waterproof implant, cable in Loose tube layer 3
Core center is a metallic strength member being cladded with polyethylene, and Loose tube layer 3 is around compact stranded conglobate of center strengthening core
Cable core, the gap in cable core is blocked water implant, extrudes layer of polyethylene inner sheath 8, double sheaths after the vertical bag of plastic-coated aluminium strip APL
Double armature structure, lateral pressure resistant function admirable, outer protective polyethylene jacket layer 6 has the most resistance and harmony, composite steel-plastic belt 5 to indulge
Bag effectively raises the anti-moisture vapor transmission ability of optical cable, and polyethylene inner sheath 8 plays the duplicate protection to optical cable, plastic-coated aluminium strip APL
Having good shielding and moisture protection, Loose tube layer 3 material itself possesses good hydrolytic resistance and higher intensity,
Being filled with waterproofing unction in pipe, optical fiber has carried out the protection of most critical, center strengthening core strengthens the collimation of optical cable and resists
Tensile strength, wear-resistant, stretch-proof, water preventing ability are good.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this
Utility model, although being described in detail this utility model with reference to previous embodiment, for those skilled in the art
