Abstract
The invention discloses a bird-peck-prevention optical cable. The optical cable comprises a first outer protection sleeve and a second outer protection sleeve, wherein a central reinforcing piece, a plurality of optical fiber units and water-blocking filler are arranged in the first outer protection sleeve; a non-metallic reinforcing layer is arranged between the first outer protection sleeve and the second outer protection sleeve; a plurality of color bars in at least two colors are evenly distributed and embedded in the outer circumferential surface of the second outer protection sleeve, different colors of the color bars in at least two colors are arranged alternately, and the color bars in at least two colors extend in the axial direction of the optical cable. According to the optical cable, the plurality of color bars extending in the axial direction of the optical cable are embedded in the outer circumferential surface of the second outer protection sleeve, so that the optical cable with better bird-peck-prevention performance is obtained in the aspects of the bionics principle and the structure material texture.
Description
Technical field
The present invention relates to a kind of communication facilities, particularly relate to a kind of optical cable.
Background technology
At home, all erecting communication optical cables under a lot of power circuit, is All Dielectric self-support (abbreviation ADSS) in general industry.A lot of power circuit is all through field, wilderness, and just past on bird sanctuary or migratory bird moving circuit, birds are liked standing on optical cable and have a rest, and some kind is liked pecking optical cable.And cable jacket is the polyethylene layer of one deck 1.8 mm of thickness, hardness is general, is easy to just be pipped by birds, and then affects optical cable tensile performance, make optical cable inner fiber forced breakage, communication disruption, impacts to people's life, sometimes catastrophic especially.
At present, in bird pest area, optical cable damage is very serious, and almost all will again set up new optical cable every year, this brings very big puzzlement to power department, at substantial manpower and materials, and communication is interrupted often, causes immeasurable loss.A kind of anti-unfirmly closing optical cable is needed, to separate the matter of great urgency so eager.Some producers copy the method for termite-resistant rodent-resistant, and produce some anti-unfirmly closing optical cables, effect is all undesirable.Because they adopt chemical method, namely in sheath material, add a kind of pungent substance, allow birds away from, but this optical cable, along with passage of time, pungent taste is slowly thin out, just invalid after usual half a year.And this optical cable is pungent, stimulate the skin of people, harmful, not environmentally.
Summary of the invention
Technical matters to be solved by this invention to provide a kind of anti-unfirmly closing performance better optical cable.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of anti-unfirmly closing optical cable, comprise the first oversheath and the second oversheath, central reinforce member, some fiber units and the filling material that blocks water is provided with in the first described oversheath, described fiber unit is arranged around central reinforce member, the second described oversheath parcel is arranged at outside the first described oversheath, is provided with non-metal reinforced layer between the first described oversheath and the second oversheath; The outer peripheral face of the second described oversheath is embedded with the colour bar of some at least two kinds of colors evenly distributedly, the alternate setting of colour bar different color of at least two kinds of described colors, the color of the colour bar of described at least two kinds of colors is different from the color of described second oversheath, and the colour bar of described at least two kinds of colors extends along the axis of described optical cable.
Described fiber unit can be loose tube fiber.
The non-metal reinforced layer arranged between the first described oversheath and the second oversheath can be aramid layers or glass yarn layer.
Described central reinforce member periphery also can be wrapped up and is provided with central reinforce member bed course.
The width of the colour bar of at least two kinds of described colors 0.5 ~ 3.0 millimeter, the outer peripheral face of described second oversheath is provided with at least evenly distributedly 6 colour bars.
The colour bar of described at least two kinds of colors extends or spiral extension along the axial straight line of described optical cable.
More excellent, the colour bar of at least two kinds of described colors selects intensity to be better than the material of the second oversheath.
Anti-unfirmly closing optical cable of the present invention by being embedded some along the axially extended colour bar of optical cable in the extrusion of the second oversheath on the outer peripheral face of the second oversheath, thus obtains the better optical cable of anti-unfirmly closing performance.We know that most birds eyesight is fine, and have stereoscopic vision, distinguishing colours is very capable, and has the function of dual regulation focal length, fears alternate color.Because snake is the natural enemy of bird, usual birds all can be afraid of snake, utilize bionics principle to reach anti-unfirmly closing function; And being embedded different colour bars at the outer peripheral face of the second oversheath in sheathing technique outside, also to make the outer peripheral face of the second oversheath more not easily be pecked from material texture bad.
The width of colour bar 0.5 ~ 3.0 millimeter, the outer peripheral face of the second oversheath is at least provided with 6 colour bars.So no matter which portion perimeter of optical cable faces up, or no matter birds from which direction of optical cable are observed, and all can see at least 3 colour bars, concerning more easily causing their fear birds.And straight line extends or the colour bar of spiral extension can allow birds produce the illusion of the snake of parade or the snake of coiling.
And after colour bar selects intensity to be better than the material of the second oversheath; just that to be provided with a high strength catch net the same seemingly at the outer peripheral face of the second oversheath, this difference of material texture and the ceiling of high strength be arranged so that the outside surface intensity of optical cable higher, more not easily like by birds, more not easily pecked bad by birds.
