Abstract
The invention relates to a miniature high-strength flexible optical cable. The miniature high-strength flexible optical cable includes a cable core and an outer sheath, and is characterized in that the cable core is wrapped in an ultrathin inner sheath, a nonmetal outer reinforced layer is laid outside the ultrathin inner sheath, and the outer sheath wraps the nonmetal outer reinforced layer. The miniature high-strength flexible optical cable is large in number of cores, thin in outer diameter, light in weight and excellent in bending performance, saves wiring space resources, and reduces construction cost; the optical cable has good weather resistance and mechanical property, and satisfies using requirements of multiple fields such as pipelines, indoor, short-distance overhead, jumper wire manufacture, machine rooms, medical treatment, wind power industry and so on; and the optical cable is of an all-dry type structure, all units are arranged reasonably, and the optical cable adapts to requirements for the outer diameter dimension, bending radius and tensile strength of the optical cable in a severe communication environment. A cable opening rope is arranged between the inner and outer sheaths, thereby facilitating direct access to a room after the outer sheath is removed to perform diverging connection, and the miniature high-strength flexible optical cable is more convenient to use and lay.
Description
Technical field
The present invention relates to a kind of miniature high strength flexible optical cable, be specifically related to a kind of tensile property and the excellent high strength micro optical fiber cable of weather resistance.
Background technology
In recent years, along with optical fiber communication, to FTTB(, Fiber To The Building), FTTO(Fiber-To-The-Office), FTTH(fiber-to-the-home front yard) etc. the development in direction, and user is more and more higher to the requirement of the aspect such as room, fiber to the desk to optical fiber, micro optical cable obtains and develops rapidly, and each optical cable manufacturer also increases the input to micro optical cable research and development and production.But more or less there are some problems in the micro optical cable occurred in the market.On the one hand in existing indoor micro optical cable, contained fiber number is less and only have one deck sheath, although have less bending radius, its transmission capacity, weather resistance and tensile property can not meet the cabling requirement of the occasions such as high capacity data transmission, built on stilts, severe communication environment; Although existing outdoor micro optical cable has the high advantage of fiber number on the other hand, but because it adopts steel wire or other stiffeners as reinforcement, bending radius is large, machine room, multi-media classroom etc. comparatively narrow space or pipeline wiring time, affect optical cable to use, waste conduit resource, even can cause optical fibre in optical cable to rupture.
Although described in Chinese patent 2010205003289.6, optical cable size is little, good bending property, its tensile property and weather resistance poor, the request for utilization under more severe communication environment can not be met.Optical cable described in Chinese patent 201220149546.X adopts spiral armour tubular construction, though compressive property and tensile property excellent, cable size is comparatively large, optical cable Heavy Weight, is unfavorable for cable runs user demand under small space.
Summary of the invention
Technical matters to be solved by this invention is the deficiency that exists for above-mentioned prior art and proposes a kind of miniature high strength flexible optical cable, and not only fiber number is many for it, external diameter thin, but also has excellent mechanical property, weather resistance and bending property.
The technical scheme that the problem that the present invention is the above-mentioned proposition of solution adopts is: include cable core and oversheath, it is characterized in that described cable core is coated in ultra-thin inner sheath, nonmetal outer enhancement Layer is laid with, nonmetal outer enhancement Layer outer cladding oversheath outside ultra-thin inner sheath.
By such scheme, between ultra-thin inner sheath and cable core, be provided with nonmetal interior enhancement Layer.
By such scheme, described cable core includes 1 ~ 12 colored optical fiber.
By such scheme, the described monolateral wall thickness of ultra-thin inner sheath is 0.05 ~ 0.08mm.
By such scheme, described ultra-thin inner sheath is made up of photo-curing materials such as unsaturated polyester (UP), epoxy acrylate, urethane acrylate, polyester acrylate, polyether acrylate, acroleic acid esterification polyacrylic resin or epoxy resin.
By such scheme, described nonmetal outer enhancement Layer and nonmetal interior enhancement Layer are formed by aramid yarn or glass fiber yarn.
By such scheme, the monolateral wall thickness of described oversheath is 0.25 ~ 0.30mm.
By such scheme, described oversheath external diameter is less than or equal to 4mm; Also hawser is provided with out in oversheath.
By such scheme, described oversheath is made up of the macromolecular material of the mechanical property such as polyurethane, fluoroplastic and weather resistance excellence.
By such scheme, the tensile strength of described optical cable is more than or equal to 400MPa.
By such scheme, described optical cable static buckling radius is less than 30mm, and dynamic bending radius is less than 60mm.
Beneficial effect of the present invention is: 1, core number is many, external diameter thin, and lightweight, bending property is excellent, has saved wiring space resource, has reduced construction cost; 2, be provided with inside and outside two-layer sheath and inside and outside two-layer reinforcing element respectively, optical cable has good weather resistance and mechanical property, meets the multi-field user demands such as pipeline, indoor, short distance are built on stilts, wire jumper making, machine room, medical treatment, wind-powered electricity generation industry; 3, dry type structure, each unit is arranged rationally, adapts to the requirement to cable outer diameter size, bending radius, tensile strength under severe communication environment.Arrange between interior oversheath simultaneously and open hawser, after being convenient to remove oversheath, directly access indoor are carried out difference and are continued, use lay more convenient.
