In the present invention, due to pecking layer with anti-, anti-layer of pecking has special formula, and on the one hand it can be entered by extruding machine
Row extrusion molding, easy to process, speed of production is fast, and a diameter of below 25mm cable and optical cable, speed are produced on the extruding machines of φ 90
More than 60 ms/min are reached, and product qualified rate is high, because anti-peck has ultra-fine steel fibre and glass fibre and titanium dioxide in layer
Silicon optical fiber, it has extremely strong performance of stabbing, and birds peck hitting after first time, will injure its puff, therefore do not peck again
The desire hit so that cable is effectively protected, by the use in nearly 3 years forest zones, does not have generation because birds peck bad optical cable again
And the accident for interrupting communication occurs;Meanwhile, anti-layer of pecking of the invention is with stronger anti-side pressure and impact resistance.Extra-fine steel is fine
Dimension or glass fibre are commercially just commercially available, and for the anti-silica optical fiber pecked in layer, can purchase light guide fine
Dimension is rolled, crushed, filtering acquisition, can not only be used light guide fibrous finished product, can also be used no covering or not coat
Layer or optical fiber fibre core or silica optical fiber core body without covering and coat and dyed layer, it might even be possible to use light guide
Fiber waste product is rolled, crushed, filtering acquisition, is reached the useless purpose utilized, is reduced the pollution of optical fiber producer;In addition, this hair
Material and product in bright are not related to problem of environmental pollution.
The present invention is easy to the equipment for making, need not adding costliness.
In the present invention, when having overcoat, overcoat with it is anti-peck layer and resist pecking for birds jointly hit, when there is no overcoat, plus
Strong part with it is anti-peck layer and resist pecking for birds jointly hit, make optical cable resist peck hit, impact, the performance of pressure-resistant aspect is greatly increased.
In the present invention, oversheath can try one's best without using expensive nylon, can so cost is declined to a great extent, make
The buying of user, safeguard that integrated cost is lower.
Certainly, the oversheath in the present invention can also use coloured sheath, such as red, yellow etc., preferably still
Conventional black.
The present invention has following main beneficial effect:Easily make, it is anti-peck that effect is good, speed of production is fast, product qualified rate is high,
More resistant to pressure and more resistant to impact.
Applicant has made using contrast, light for the anti-unfirmly closing optical cable in the application and the optical cable produced by prior art
Cable is all to make somebody a mere figurehead to lay, and the structure for all using embodiment 1 of the invention, oversheath is black and red, and 1#-4# represents different
It is anti-peck layer formula, 1# is maximum magnitude, wherein the ratio of weight and number of ultra-fine steel fibre, glass fibre, silica optical fiber
For (1~2):(1~2):(4~8);2# is optimal implementation formula, wherein ultra-fine steel fibre, glass fibre, silica optical fiber
Ratio of weight and number be 1:1:8;3# is that suboptimum implements formula, wherein the weight of ultra-fine steel fibre, glass fibre, silica optical fiber
It is 1 to measure portion rate:1:3;4# is more excellent implementation formula, wherein the parts by weight of ultra-fine steel fibre, glass fibre, silica optical fiber
Number is than being 1:1:1;Control group is 5#, uses the structure of embodiment 1, and only it prevents pecking layer, but oversheath
Thickness adds for the oversheath thickness of embodiment 1 of the present invention to be prevented pecking thickness degree, and oversheath is red, and each sequence number is same in Hunan
Forest zone respectively uses 100 kilometers, obtains following data.
From upper table, it is apparent that using the present invention, due to the anti-effect for pecking layer, really obtaining electric power, communications
Ensure, meanwhile, anti-peck in layer pecks best performance using more anti-of silica optical fiber content;Moreover, oversheath is coloured
When, pecking for birds is more subject on the contrary to be hit.
Applicant has also carried out same contrast test to other embodiments, and result of the test is basically identical;In the present invention
Anti- layer of pecking is by test, and its performance is all higher than the minimum performance requirement of optical cable, the industry of cable jacket material and national standard, plus
Work function admirable.
The present invention is not limited to above-mentioned preferred forms, it will be appreciated that design of the invention can be by other a variety of shapes
