Abstract

The utility model discloses a butterfly optical cable, include: tight coated fibers, first intensity component, second intensity component, sheath, first dampproof course, toughness enhancement layer and second dampproof course, transversal 8 styles of calligraphy of personally submitting of sheath, first intensity component and second intensity component two centres of a circle that lie in 8 styles of calligraphy respectively, tight coated fibers be located first intensity component and second intensity component in the middle of, tight coated fibers outer from interior toward having set gradually outward first dampproof course, toughness enhancement layer and second dampproof course. In this way, the utility model provides the dampproof and waterproof characteristic of high optical cable, mechanical properties is good, can carry out the essence protection to optic fibre, effectively lengthens its life.

Description

Butterfly optical cable

Technical field

The utility model is related to optical cable field, more particularly to a kind of butterfly optical cable.

Background technology

Butterfly optical cable is a kind of novel user access optical cable, different with laid condition according to applied environment, appropriate design light Cable structure and every technical parameter, have gathered the feature of indoor flexible optical cable and self-support cable, have coordinated import using special equipment Precision die produces.It is that fttx network solves optimal alternate product, setting up intelligent Building, digital cells, campus network, local The effect of its uniqueness is played in the networks such as net.

But in traditional butterfly optical cable, the coated fiber (being commonly called as naked fibre) being placed in optical cable center is no appointed in centre bore What is protected, and during Long-Time Service, in the presence of the erosion of in the air moisture and bending stress, can make coating and optical fiber Depart from, optical fiber will completely lose intensity, thus its service life is placed restrictions on, and this traditional covered wire cable is in mechanicalness Can go up and can not carry out essence protection to optical fiber.

Utility model content

, mainly solving the technical problems that providing a kind of butterfly optical cable, the moistureproof and waterproof improving optical cable is special for the utility model Property, good mechanical property, optical fiber can be carried out with essence protection, effectively extend its service life.

For solving above-mentioned technical problem, the technical scheme that the utility model adopts is: provides a kind of butterfly optical cable, bag Include: tightly packaged fiber, the first strength members, the second strength members, sheath, the first damp-proof layer, toughness enhancement layer and the second damp-proof layer, The cross section of described sheath is in 8 fonts, and the first described strength members and the second strength members are respectively positioned at two circles of 8 fonts The heart, described tightly packaged fiber is located in the middle of the first described strength members and the second strength members, described tightly packaged fiber outer from Inside it is disposed with the first described damp-proof layer, toughness enhancement layer and the second damp-proof layer outward.

In one preferred embodiment of the utility model, the first described strength members are aramid fiber reinforcing core.

In one preferred embodiment of the utility model, the second described strength members are carbon fiber strengthening core.

In one preferred embodiment of the utility model, the first described damp-proof layer is double plastic-coated aluminium strip.

In one preferred embodiment of the utility model, described toughness enhancement layer is pc/pbt blended compound material layer.

In one preferred embodiment of the utility model, the second described damp-proof layer is that the micropore of expanded PTFE is thin Film layer.

The beneficial effects of the utility model are: the utility model improves the moistureproof and waterproof characteristic of optical cable, good mechanical property, energy Essence protection is carried out to optical fiber, effectively extends its service life.
