Abstract
The present invention relates to an optical cable for communication network, and specifically to a UV optical cable which comprises a central reinforcement, a plurality of optical fiber bundles twisted around the central reinforcement, and the sleeves coated on the peripheral surface of the plurality of optical fiber bundles. Each optical fiber bundle is formed by a plurality of optical fibers which are alternately fixed in the UV curing resin with a beam shape. The invention uses the UV optical fiber bundle as an optical fiber unit. The clearance between the optical fibers in the UV optical fiber bundle is filled by UV cured resin. The diameter of optical cable is greatly reduced. The density of optical cable is increased. The optical cable for communication network has the advantages of small diameter, light weight, high production rate, convenient and quick welding, etc. The pipe wiring of optical cable in the building greatly saves the resource of pipe and furthermore facilitates the optical fiber branching without cutting off the optical fiber. The optical cable of the invention is a novel optical cable for aiming at the FTTH communication network construction.
Description
Technical field
The present invention relates to a kind of communication network optical cable, particularly relate to a kind of UV optical cable.
Background technology
In the FTTH implementation process, the optical cable wiring is the more problem of paying close attention in the FTTH networking.Existing cable configuration, material, production technology are optimized, can improve optical cable production efficiency, reduce the optical cable production cost, improve the optical cable wiring method, can better satisfy the requirement of FTTH networking, promote FTTH popularizing in China.
At present, the fiber unit of Access Network outdoor optical cable mainly contains following several structure.
A kind of structure is to adopt the loose sleeve structure of factice for filling, and multifiber is randomly dispersed in the loose sleeve pipe of factice for filling, this structure, and when optical cable construction or environment changed, fiber position can relatively move.In order to guarantee that optical cable does not produce excessive strain or too small bending when changing and produces decay at construction or environment, the pine sleeve pipe must have bigger external diameter, cause whole cable outer diameter big like this, the optical cable cost also can be very high, and this optical cable can only carry out the single fiber welding, has caused very big inconvenience to cable connection.
Second kind of structure is to adopt band structure of optic fibre, and multifiber is distributed in the resin of ultraviolet light polymerization side by side, and fibre ribbon is banded, has less thickness, but the fibre ribbon broad.Use the optical cable of this fibre ribbon production because the fibre ribbon broad so the optic cable diameter of producing is bigger, is unfavorable for making full use of of conduit resource.Though this fibre ribbon can 12 optical fiber weldings together, because the fiber bandwidth height ratio is very big, so can make fibre ribbon transition distortion or bending the time optical fiber on the limit produce very big decay.
The third structure is to adopt the tight tube fiber structure, and this structure is directly to extrude one deck macromolecular material outside optical fiber, and this structure has advantages such as diameter is little, in light weight, flexibility is good.But this tight tube fiber structure only is applicable to an optical fiber, and speed of production is relatively slow, and when an optical cable need be used a large amount of tight tube fiber, the diameter of optical cable can be relatively large.
Summary of the invention
Technical matters to be solved by this invention is that the solution optic cable diameter is big, the problem of the inconvenience that continues.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention provides a kind of UV optical cable, sheath on fibre bundle that comprises a central reinforce member, is made up of some optical fiber around central reinforce member stranded some and the outer surface that is coated on described some fibre bundles, some optical fiber fasciculation fixed interval in the described fibre bundle are in the inside of UV-cured resin.
In the such scheme, the cross section of described fibre bundle is circular.
Wrapped water blocking yarn on the described central reinforce member.
Some fibre bundles are stranded in outsourcing waterstop behind the central reinforce member.
Be provided with attached reinforcement between described waterstop and the sheath.
The quantity of optical fiber is 3～12 in the described fibre bundle.
The quantity of optical fiber is 3～12 in the described fibre bundle.
Described central reinforce member is steel wire or FRP.
Described waterstop is single face waterstop, two-sided waterstop, multiple film single face waterstop or the multiple two-sided waterstop of film.
Described attached reinforcement is a kind of in glass fibre, the aramid fiber, or mixing for above-mentioned two kinds of fibers.
Described sheath is tygon, Polyvinylchloride, polyurethane, low smoke and zero halogen plastics LSZH or nylon.
The present invention, use the UV fibre bundle as fiber unit, this UV fibre bundle is fixed on by some optical fiber in the resin of ultraviolet light polymerization and forms, space in the whole UV fibre bundle between each optical fiber is filled by the resin of ultraviolet light polymerization, reduced optic cable diameter greatly, improve density of optic fibre, had advantages such as diameter is little, in light weight, speed of production fast, convenient quick welding.This optical cable has been saved conduit resource greatly in building, building interior conduit wiring, and helps not cutting off optical cable and carry out the optical fiber difference, is a kind of brand-new optical cable at the FTTH communication network development.
