Abstract
The invention relates to a talcum powder-filled central tube type novel indoor optical cable with a plurality of optical fiber bands, belonging to the technical field of manufacturing of a communication optical cable product. The talcum powder-filled central tube type novel indoor optical cable consists of the optical fiber bands, talcum powder, a PBT (polybutylece terephthalate) loose sleeve, a flame-retardant sheath and the like. At first, the optical fiber bands are formed by binding of a plurality of optical fibers and are then stacked and spirally twisted, the PBT loose sleeve is sleeved outside the twisted optical fiber bands, aramid yarns are wound and the flame-retardant sheath is sleeved. The talcum powder is filled among the optical fiber bands and between the optical fiber bands and the inner wall of the PBT loose sleeve. The novel indoor optical cable has the advantages of light weight, large density of optical fibers, excellent performance and low manufacturing cost, outdoor performance index requirements of an ointment-filled optical fiber with optical fiber bands can be satisfied, and the novel indoor optical cable is also suitable for vertical and horizontal laying in buildings. The following problems can be solved: the existing ointment-filled optical fiber with optical fiber bands is not suitable for indoor vertical laying, ointment in the loose sleeve can drop naturally under effects of the gravity after long-term use, the environment can be polluted and the transmission performance of optical fibers can be affected.
Description
Technical field
The present invention relates to a kind of many fibre ribbons of talc central tubular Novel indoor optic cable, belong to communications optical cable product manufacturing technology field.
Background technology
Optical fibre band optical cable has high density, compact conformation, is convenient to fast splicing, is easy to the advantages such as branch, at present, it is the ointment of filling in the common loose casing fiber optic band optical cable, to guarantee between the fibre ribbon and fibre ribbon in the loose sleeve pipe, the infiltration of good lubricated and prevention water is arranged between fibre ribbon and the loose internal surface of sleeve pipe, but the optical fibre band optical cable of ointment filled type is not suitable for indoor vertical run, such as vertical run, ointment in long-term the use in the loose sleeve pipe can be under action of gravitation natural drip, contaminated environment affects the transmission performance of optical fiber.
Summary of the invention
The object of the invention is to, provide a kind of employing talcum powder between loose casing fiber optic band, to fill, effectively improve the decay indices main performance of the Optical Fiber Transmission of optical cable, make decay indices be better than many optical fiber ribbon indoor optical cables of other filling modes; Can reach ointment and fill the outdoor performance index of many optical fibre band optical cables, can be suitable for again vertical in the building and horizontal laying, be many fibre ribbons of talc central tubular Novel indoor optic cable that indoor optical cable provides that a kind of density of optic fibre is large, superior performance, long-term vertical use can natural drips.
The present invention realizes above-mentioned purpose by the following technical solutions:
A kind of many fibre ribbons of talc central tubular Novel indoor optic cable, it is comprised of optical fiber, fibre ribbon, talcum powder, PBT pine sleeve pipe, aramid yarn and fire retardant jacket, it is characterized in that, described fibre ribbon is passed through by 4 ~ 24 optical fiber and band forms, and is printed on identification code on the fibre ribbon; Stranded by the spiral twisting pitch of setting after fibre ribbon is stacked together, the outer surface cover of fibre ribbon after stranded is surrounded by PBT pine sleeve pipe, and PBT pine sleeve pipe overcoat is surrounded by fire retardant jacket; Between described fibre ribbon and the fibre ribbon, be filled with talcum powder between the inwall of fibre ribbon and PBT pine sleeve pipe, be wound with aramid yarn by the screw pitch of setting between described PBT pine sleeve pipe and the fire retardant jacket.
The present invention's beneficial effect compared with prior art is:
This many fibre ribbons of talc central tubular Novel indoor optic cable structure is little, lightweight, and density of optic fibre is large, superior performance, and low cost of manufacture, processing technology is simple.Can reach the outdoor performance index request of the optical fibre band optical cable of ointment filling, can be suitable for again vertical in the building and horizontal laying, long-term vertically use can natural drip.Solved existing ointment filled type optical fibre band optical cable and be not suitable for indoor vertical run, as vertical run in long-term the use ointment in the loose sleeve pipe can be under action of gravitation natural drip, contaminated environment affects the problem of Optical Fiber Transmission performance.
Description of drawings:
Accompanying drawing is a kind of structural representation of many fibre ribbons of talc central tubular Novel indoor optic cable.
Among the figure: 1, optical fiber, 2, fibre ribbon, 3, talcum powder, 4, PBT pine sleeve pipe, 5, aramid yarn, 6, fire retardant jacket.
Embodiment:
That the invention will be further described is as follows below in conjunction with accompanying drawing:
This many fibre ribbons of talc central tubular Novel indoor optic cable is comprised of optical fiber 1, fibre ribbon 2, talcum powder 3, PBT pine sleeve pipe 4, aramid yarn 5 and fire retardant jacket 6, described fibre ribbon 2 by 4 ~ 24 optical fiber 1 by and the band form, be printed on identification code on the fibre ribbon 2.After the many fibre ribbons 2 that are printed on the different identification code are stacked together, undertaken strandedly by the spiral twisting pitch of setting, the outer surface cover of the fibre ribbon 2 after stranded is surrounded by PBT pine sleeve pipe 4, and PBT pine sleeve pipe 4 overcoats are surrounded by fire retardant jacket 6.Between described fibre ribbon 2 and the fibre ribbon 2, be filled with talcum powder 3 between the inwall of fibre ribbon 2 and PBT pine sleeve pipe 4; Be wound with aramid yarn 5 by the screw pitch of setting between described PBT pine sleeve pipe 4 and the fire retardant jacket 6.
When this many fibre ribbons of talc central tubular Novel indoor optic cable is made, first with multifiber 1 by and the mode of band make and form fibre ribbon 2, and be printed on identification code at fibre ribbon 2.After the more fibre ribbons 2 that are printed on the different identification code being stacked together, between fibre ribbon 2 and fibre ribbon 2, fill talcum powder 3, then by conduit fibre ribbon 2 combination is imported in the PBT pine sleeve pipe 4 by extruder for shaping, form between fibre ribbon 2 and the fibre ribbon 2, be filled with the loose sleeve pipes of many fibre ribbons of talcum powder 3 between the inwall of fibre ribbon 2 and the loose sleeve pipe 4 of PBT.Enter again the sheath operation, loose sleeve pipe is emitted by pay off rack, pass the winding machine of aramid yarn 5, aramid yarn 5 emitted from winding machine and be wrapped in spirally around the loose sleeve pipe with the spiral twisting pitch of setting, then penetrate extruder head and extrude one deck fire retardant jacket 6, namely make many fibre ribbons of talc central tubular Novel indoor optic cable product.
