Abstract

The utility model relates to an optical cable with identification lines which can be identified quickly, thereby being convenient for paving. The utility model comprises a cable core and an outer sleeve. Compared with the traditional optical cable, the utility model is characterized in that one or a plurality of identification lines are arranged on the outer sleeve along the longitudinal direction. The identification line can take a straight line, a wave line or a helix line. The identification line can also take a strip embedding line which has different color with the outer sleeve. Generally speaking, the quantity of the identification line is approximately one to three. The plurality of identification lines can take same color or different colors. The beneficial effect of the utility model is that first, the outer sleeve of the optical cable is provided with an identification line, which is convenient for identifying, so that the optical cable can be identified quickly when pave or maintain the optical cable in a multi-optical cables channel or in the same pipeline, thereby being convenient for operation and construction; and second, the identification lines are the outer sleeve are embedded in to a whole, and the identification lines can not fade and disappear due to outside construction abrasion and outside environment dirt, thereby remaining a long identification performance.

Description

The optical cable that has tag line

Technical field

The utility model relates to a kind of can identification rapidly so that the optical cable that has tag line of cabling construction.

Background technology

Along with the development of communications industry, the use of optical cable is increasingly extensive, and the amount of fiber cable laying also increases day by day.Existing optical cable mostly has optical cable core, sheath and oversheath to constitute, oversheath is the outmost integument of optical cable, be generally with a kind of color, though outside the oversheath of optical cable, print at interval some labelled notations arranged, but distinctiveness is not strong, when many optical cables during with ditch or same pipeline laying, the problem obscuring and be difficult for distinguishing can appear, and brought inconvenience for construction and later maintenance.

Summary of the invention

Problem to be solved in the utility model is to provide a kind of optical cable that can discern rapidly, be convenient to construct at the deficiency of prior art existence.

For solving the problem of above-mentioned proposition, the technical solution adopted in the utility model is: include optical cable core 4 and oversheath 2, its difference is on oversheath along vertically being provided with one or more tag line 1.

Press such scheme, described tag line 1 can be straight line or wave molding or helix; Tag line can be with the different strip of oversheath color inlays line; Usually tag line is 1～3; The color of many colour-marking lines can be homochromy or heterochromatic.

Good effect of the present utility model is: 1, on the oversheath of optical cable, tag line is set, is easy to distinguish, many optical cables with the continued access of ditch or same pipeline laying and optical cable, can discern rapidly when safeguarding, so that operation and construction; 2, tag line and oversheath are set into one, can not lose because of the dirt of construction wearing and tearing and external environment and desalinate and loss, and can keep the permanent recognition performance that is easy to.

Embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

First embodiment such as Fig. 1, shown in 2, include optical cable core 4, optical cable core can be layer-twisted type, central tubular, various structure cable cores such as skeleton, be wrapped with sheath 3 at optical cable core, outside sheath, be enclosed with oversheath 2 again, on the outer surface layer of oversheath, longitudinally be inlaid with the tag line 1 of straight line type, tag line and optical cable are with long, the color of tag line and oversheath color are different, and the obvious contrast of tool, and tag line and oversheath can be made with commaterial, the width of tag line can be 0.01-10mm, be generally 0.10-2mm, thickness can be 0.10mm-oversheath thickness, and tag line and oversheath are inlayed and be combined into one.

Second embodiment is shown in Fig. 3,4, the main difference part of it and last embodiment is longitudinally to inlay two linear tag lines 1 on the extexine of the oversheath 2 of optical cable, article two, the color of tag line is different and different with the oversheath color, and other parts are identical with a last embodiment.

The 3rd embodiment is shown in Fig. 5,6, and its principal feature is longitudinally to stud with the tag line 1 of a ripple line style on the extexine of the oversheath of optical cable, and wave molding can be sinusoidal waveform, and other parts are identical with first embodiment.
