Brief description of the drawings
Fig. 1 is a kind of structural representation of high density Lightweight nonmetal optical fiber cable for field operation of the present utility model.
Reference：
Oversheath 1；
Aramid fiber obturator 2；
Colored optical fiber 3, core 31, aramid fiber braiding layer 32, polyacrylic acid ester layer 33.
Embodiment
The utility model is described in detail below in conjunction with specific embodiment and accompanying drawing.
A kind of high density Lightweight nonmetal optical fiber cable for field operation of the present embodiment, as shown in figure 1, being fire-retardant TPU's including material
The colored optical fiber 3 that oversheath 1 that external diameter is 3 ~ 4 millimeters and 12 external diameters for being arranged in oversheath 1 are 0.25 millimeter, it is preferred that
The external diameter of oversheath 1 is 3.0mm scholar 0.1mm, colored optical fiber 3 include core 31, coat the polyacrylic acid ester layer 33 of core 31 with
And it is 0.4 ~ 0.5 millimeter of aramid fiber braiding layer 32 to be directly coated on the external diameter of polyacrylic acid ester layer 33, single colored optical fiber 3
To bear 5 ~ 8KG pulling force, more than 50N/10cm compression strength；Preferably, core 31 is graded refractive index glass core
31.In terms of the arrangement of colored optical fiber 3,12 colored optical fibers 3 are layered on top of each other setting, wherein four are arranged in a row and the coloring at both ends
Optical fiber 3 props up the inner side of oversheath 1, and colored optical fiber 3 pushes against the inner side of oversheath 1 and can prevent from shifting to a certain extent, colored optical fiber 3
Between mutually push against, structure is more compact.12 colored optical fibers 3 are mutually twisted to be set, and between adjacent two colored optical fibers 3
Fitting is set；Between oversheath 1 and colored optical fiber 3, aramid fiber obturator 2 is filled between adjacent two colored optical fibers 3, it is existing
Because existing process limits in technology, it is mutually twisted and it is typically no between the colored optical fiber 3 of fitting be filled with other things,
So frequently can lead to it is twisted after colored optical fiber 3 it is easily loose, structure is not compact enough, and its mechanical performance does not reach requirement yet,
Broken string phenomenon is frequently resulted in, and is filled with aramid fiber between adjacent two colored optical fibers 3 in the present embodiment and is twisted again, Neng Gou great
It is big to improve disconnection problem, with reference to outside the polyacrylic acid ester layer 33 and aramid fiber braiding layer 32 that directly coat of core 31, its tension
Intensity has reached more than 1000N, and compression strength has reached more than 2000N/10cm, considerably beyond wanting for optical fiber cable for field operation standard
Ask.It is most important, the overall weight of optical cable only have 7.5KG/KM less than, the ratio of strength to weight of superelevation and the up to number of fibers of 12 cores,
Integrated level is very high.
Compared with prior art, the utility model due in the outside of core 31 directly by polyacrylic acid ester layer 33 and aramid fiber
Braiding layer 32 coats, therefore can largely reduce the diameter of colored optical fiber 3；And 12 colored optical fibers 3 are mutually twisted
Set, between oversheath 1 and colored optical fiber 3, aramid fiber obturator 2 is filled between adjacent two colored optical fibers 3, with reference to outside
TPU materials oversheath 1, it is possible to increase the tension and compression strength of optical cable, its performance can exceed optical fiber cable for field operation requirement.Pass
The nonmetallic optical fiber cable for field operation of system, the external diameter of 4 cores also want 5.2mm, and weight reaches 24kg/km, and tensile strength does not reach 1000N, phase
Than under, optical cable of the present utility model has obviously advantage, with tension stress is strong, compressive resistance is strong, flexibility is good, bending resistance
Song, oil resistant, it is wear-resisting, fire-retardant, temperature applicable range is wide the features such as；High integration, high-mechanical property, high intensity, without metal armouring
Structure, be professional precise guidance, warship with the transmission cable of, tank, be highly suitable for military outdoor communication system fast wiring
Or folding and unfolding uses repeatedly.
Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality
With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general
It is logical it will be appreciated by the skilled person that can be modified to the technical solution of the utility model or equivalent substitution, without departing from this
The spirit and scope of utility model technical scheme.
