Description
Technical field
The present invention relates to fiber optic cable manufacture detection technique field, be specifically related to a kind of device and detection method thereof of fast detecting optical cable infiltration.
Background technology
The permeability performance test of optical cable is a key project in optical cable environmental performance always, carrying forward vigorously and expanding along with national information engineering, at present the system of laying of optical cable presents taking pipeline and direct-burried as main, and outdoor making somebody a mere figurehead is auxiliary general layout, and the permeability performance of optical cable just seems and is even more important.Optical cable uses having under water or moisture environment for a long time, can cause the water peak decay of optical fiber, simultaneously can be by permeating corrosion effect, the micro-crack that causes optical fiber surface constantly expansion until fibercuts; Infiltration also can be corroded the metal reinforcement in optical cable, and reacts and cause the hydrogen loss of optical fiber with metal material, affects usability and the life-span of optical cable; Optical cable infiltration does not add control, and water can, along Cable Core longtitudinal dispersion to being connected box or going back to device etc., cause communication system traffic to interrupt.
The measure of optical cable water-impervious mainly contains vertical and horizontal, mainly contains fine cream, cable cream, waterstop, water blocking yarn, sleeve pipe, pitch, oversheath etc. and blocks water.In production, optical cable infiltration inspection just seems and is even more important, according to the industry standard YD/T901-2009 of People's Republic of China (PRC) layer-twisted type outdoor optical cable for communication, YD/T769-2010 central tubular outdoor optical cable for communication, GB/T7424.1-2003 optical cable generic specification part 1: general provisions and GB/T7424.2-2008 optical cable generic specification part 2: optical cable fundamental test method etc. are about the regulation of permeability performance: 3 meters of long optical cables, should flatly support, and should at (20 ± 5) DEG C temperature, apply 1 meter of high water column, 24 hours, useful water-soluble fluorescent dye or other suitable colorant detect water and leak, fluorescent dye must not react with any assembly of optical cable.
Aborning, if adopt 3 meters of long optical cables by standard, apply 1 meter of high water column, within 24 hours, observe optical cable infiltration situation, the time is oversize; In order to save time and unnecessary waste, in actual production process, optical cable infiltration detects conventionally and adopts, and 3 meters of optical cables, apply 1 meter of high water column, within 8 hours, observes optical cable infiltration situation; Or the employing time is shorter, 1 meter of optical cable, applies 1 meter of high water column, within 1 hour, observes optical cable infiltration situation, if do not seep water and detect by infiltration, if infiltration detects again by GB/T7424.2-2008 infiltration examination criteria again, more time-consuming.
The general character of several optical cable infiltration detection methods is above: optical cable infiltration is long detection time, can not immediately detect result; Testing result out after, the optical cable of having produced likely faces defective, or produce want isotonic water result out after again continue production, either way can bring no small loss to factory; And traditional optical cable infiltration device is heavier, malfunction.
