Abstract
The utility model relates to a talcum powder filling optical fiber belt center pipe novel indoor optical cable which belongs to the technical field of communication optical cable product manufacturing. The talcum powder filling optical fiber center pipe novel indoor optical cable comprises an optical fiber belt, talcum powder, a polybutylece terephthalate (PBT) loose pipe and an anti-flaming protecting sleeve. A plurality of optical fiber are formed into the optical fiber belt through combining the belt. A plurality of optical fiber belts are stacked to be hinged in a spiral mode. The PBT loose pipe is covered outside the hinged optical fiber belts. Aramid yarn and sleeved anti-flaming protecting sleeve are winded by the hinged optical fiber belts. The talcum powder filling optical fiber belt center pipe novel indoor optical cable is light in weight, large in optical fiber density, superior in performance and low in manufacturing costs. Outdoor performance index requirements of optical fiber belt optical cable filled by ointments are achieved. The talcum powder filling optical fiber belt center pipe novel indoor optical cable is suitable for laying perpendicularly and horizontally in a building. The problems that ointment filling optical fiber belt optical cable is not suitable for an indoor perpendicular laying, the ointments in the loose pipe drip naturally under a function of gravity, environment is polluted and the optical fiber transmission performance is affected are solved.
Description
Technical field
The utility model relates to a kind of many fibre ribbons of talc central tubular Novel indoor optic cable, belongs 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 purpose of this utility model is, provides a kind of employing talcum powder to fill between loose casing fiber optic band, effectively improves the decay indices main performance of the Optical Fiber Transmission of optical cable, makes 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 utility model is to realize by the following technical solutions above-mentioned purpose:
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 utility model 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 1 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 utility model will be further described is as follows below in conjunction with accompanying drawing 1:
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.
