Abstract
A manufacture method of a tight tube optical fiber combining belt indoor optical fiber cable includes that firstly a multi-core tight tube optical fiber ribbon is manufactured by using a multi-core tight tube optical fiber combining belt special internal model and an external model, a plurality of multi-core tight tube optical fiber ribbons are combined together, the multi-core tight tube optical fiber combining belt indoor optical fiber cable is formed by adding to a plurality of aramid fibers and an outer sheath, wherein the thickness of the outer sheath is 1 millimeter. Compared with the traditional technology, manufacturing cost of the manufacture method of a tight tube optical fiber combining belt indoor optical fiber cable is reduced by more than one third.
Description
Technical field
The present invention relates to the tight tube fiber inside cable, relate in particular to tight tube fiber and be with inside cable and preparation method thereof.
Background technology
Inside cable is to be to utilize single core tight tube fiber to add that aramid fiber and oversheath consist of substantially at present, Multi-core indoor optical cable is divided into two kinds substantially, a kind of is that branched cable is that tight tube fiber is added that aramid fiber and oversheath form sub-cable, and a plurality of sub-cables twist together and add that oversheath forms; Another kind is optical distribution cable, is many tight tube fibers are added that aramid fiber twists together, and adds that at last oversheath forms.Because above-mentioned inside cable is that single fuse cable or single tight tube fiber form, it is comparatively complicated that large core is counted the production process of inside cable.Invented the tight tube fiber matrix for this reason and be with inside cable, like this in the situation that equal core number, the manufacturing cost of this inside cable reduces by 1/3.
Summary of the invention
Described tight tube fiber also is to be different from the making of traditional inside cable with the method for making key of inside cable, it is to have that the multilayer tight tube fiber is stranded to be formed that traditional large core is counted inside cable, reason due to equipment, this stranded several times of wanting just can be completed, and described tight tube fiber matrix and be with inside cable only to need one-shot forming to get final product, the manufacturing cost of this inside cable reduces by 1/3.
Described tight tube fiber and be to utilize special-purpose internal mold to add that external mold produces the tight tube fiber band with the method for making of inside cable, many tight tube fiber bands 1 are combined, add some aramid fibers, add that at last oversheath just is made into the tight tube fiber matrix and is with inside cable.
Described tight tube fiber also is to utilize special-purpose internal mold to add that external mold produces multicore tight tube fiber band with the method for making key of inside cable.
Described tight tube fiber also is that with the further key of the method for making of inside cable special-purpose internal mold internal mold conduit used is concordant with the internal mold mould bases, so that wear fibre, is conducive to enhance productivity.
Described tight tube fiber also is many tight tube fiber bands 1 are combined with the method for making key of inside cable, adds some aramid fibers, forms tight tube fiber band cable core.
Described tight tube fiber and with the method for making of inside cable, the steps include: first to add that with the special-purpose internal mold of multicore tight tube fiber band external mold produces multicore tight tube fiber band, some multicore tight tube fiber bands are combined, add some aramid fibers, add that at last the thick oversheath of 1mm forms multicore tight tube fiber matrix and is with inside cable, its manufacturing cost reduces by 1/3 than the traditional fabrication method.

Embodiment
Implement one, 16 core tight tube fibers and with the making of inside cable, first with 4 core tight tube fibers and be with internal mold to add that external mold produces 4 core tight tube fiber bands, 44 core tight tube fiber bands are combined, add 16 1670detx aramid fibers, add that the thick oversheath of 1mm forms 16 core tight tube fibers and is with inside cable, its external diameter is 6.5mm.
Implement two, 36 core tight tube fibers and with the making of inside cable, first with 6 core tight tube fibers and be with internal mold to add that external mold produces 4 core tight tube fiber bands, 66 core tight tube fiber bands are combined, add 24 1670detx aramid fibers, add that the thick oversheath of 1mm forms 36 core tight tube fibers and is with inside cable, its external diameter is 9.3mm.
Claims (4)
1. described tight tube fiber and be to utilize special-purpose internal mold to add that external mold produces the tight tube fiber band with the method for making of inside cable, many tight tube fiber bands 1 are combined, add some aramid fibers, add that at last oversheath just is made into the tight tube fiber matrix and is with inside cable.
2. according to claim 1: described tight tube fiber also is characterised in that with the method for making of inside cable and utilizes special-purpose internal mold to add that external mold produces multicore tight tube fiber band.
