Abstract
The invention relates to a manufacturing technology of optical cables for a long-distance backbone network and a relay network in a communication optical cable, in particular to a novel all-medium armor optical cable. The optical armor cable comprises a plurality of optical fibers. Beam tubes cover the optical fibers, a plurality of nonmetal round rods are sequentially arrayed around the beam tubes, a nonmetal longitudinal covering band covers the nonmetal round rods, the portion between the nonmetal longitudinal covering band and the beam tubes and the portion between the nonmetal longitudinal covering band and the nonmetal round rods are filled with water blocking layers, and a sheath covers the nonmetal longitudinal covering band. According to the optical cable, the layer-stranding structure is changed into a center tube structure, and all elements in the optical cable are nonmetal; in the production process, stable excess length can be guaranteed, the influence of metal bending on the cable is avoided, and the capacity for protecting the optical fibers is high; in the construction process, shock resistance and flattening resistance are high; in the practical use process, unnecessary lightning stroke accidents can be effectively avoided, and compared with metal media, oxidation resistance and corrosion resistance are high. Through multiple experiments, transmission indexes and environment indexes of the optical cable meet the requirement.
Description
Technical field
The present invention relates to communications optical cable middle-long distance backbone network, trunk network optical cable manufacturing technology, be specifically related to a kind of Novel full medium armored optical cable.
Background technology
Optical cable adopts steel wire center to strengthen according to outer protecting after the vertical bag of definite sequence twisted synthesizing cable metal tape armouring more at present, and substantially use steel wire to do central reinforce member, beam tube adopts certain stranded mode twisted synthesizing cable outer layer metal composite belt longitudinal bag armouring sheath around central reinforce member.
Along with the fast development of domestic communications industry in recent years; Optical communication applications scope expansion.The optical cable using in long-distance backbone network, trunk network is being played the part of considerable role in whole optical cable industry.Existing armored optical cable has following shortcoming in every respect: a little less than in cable, fine determining positions is protected optical fiber ability; Be subject to metal bending and affect cable performance; Subjecting to thunder and lightning attacks; Some composition generation chemical reaction affects serviceable life easily and in soil.
Summary of the invention
For the deficiency existing in prior art, the invention provides and a kind ofly protect that strong, the lightning-arrest ability of optical fiber ability is strong, long service life, Novel full medium armored optical cable that maintenance is little.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of Novel full medium armored optical cable, it comprises some optical fiber, described optical fiber outer cladding beam tube, some nonmetal round bars are arranged in around beam tube successively, the nonmetal vertical band of nonmetal round bar outer cladding, between nonmetal vertical band and beam tube, nonmetal round bar, fill water blocking layer, nonmetal vertical band outer cladding sheath.
Above-mentioned a kind of Novel full medium armored optical cable, the optical fiber described in it is colored optical fiber.
Beneficial effect:
The present invention becomes tubular structure centered by layer-twisted type structure, and in optical cable, contained element is all nonmetal.In production, can guarantee stable remaining length, the impact of avoiding metal bending to cause cable, protection optical fiber ability is strong; In construction, shock resistance, flattening ability are strong; In actual use, can effectively avoid unnecessary lightning strike accident, compare with metal medium, anti-oxidant, corrosive power is strong.Through test of many times, its transmission objective and environmental index all meet the requirements.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the present invention in detail;
Fig. 1 is structural representation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
With reference to Fig. 1, the present invention includes some colored optical fibers 1, described optical fiber 1 outer cladding beam tube 2, some nonmetal round bars 3 are arranged in around beam tube 2 successively, the nonmetal vertical band 4 of nonmetal round bar 3 outer cladding, between nonmetal vertical band 4 and beam tube 2, nonmetal round bar 3, fill water blocking layer 5, nonmetal vertical band 4 outer cladding sheaths 6.
In the present embodiment, optical fiber is colored optical fiber, easy to use.
In structure of the present invention, by layer-twisted type, become central tubular and be more conducive to protect optical fiber; in production, can guarantee stable remaining length; prevent from causing job-hopping or side pressure optical fiber phenomenon etc. because of metal bending; eliminating many beam tube laying tension deviations causes remaining long different; in optical cable, contained element is all nonmetal; stop to draw the possibility of thunder, underground laying optical cable prevents that burning from affecting optical cable serviceable life.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
