Abstract
Способ испытаний стойкости оптического кабеля (ОК) действию замерзающей воды, заключающийся в том, что образец ОК прокладывают внутри отрезка стальной трубы так, чтобы концы ОК выходили из стальной трубы, стальную трубу по концам герметизируют и заполняют дистиллированной водой, затем образец ОК в заполненной дистиллированной водой стальной трубе помещают в климатическую камеру, через шлюз которой выводят концы образца ОК, к оптическим волокнам (ОВ) подключают средство измерений и контролируют их затухание, температуру в климатической камере изменяют в соответствии с графиком, согласно которому выдерживают образец ОК в заполненной дистиллированной водой стальной трубе при низкой отрицательной температуре до полного замерзания воды в стальной трубе, контролируют затухание ОВ в процессе испытаний и полагают, что образец ОК выдержал испытания, если изменение затухания ОВ не превышает заданного порогового значения, отличающийся тем, что образец ОК предварительно прокладывают в защитном полимерном трубопроводе (ЗПТ) так, чтобы концы ОК выходили из ЗПТ, концы ЗПТ герметизируют и ЗПТ заполняют дистиллированной водой, образец ОК в заполненном водой ЗПТ прокладывают внутри отрезка стальной трубы так, чтобы концы ОК выходили из стальной трубы, внутри стальной трубы рядом с ЗПТ укладывают демпфирующую полимерную трубку, первый конец которой герметизируют, а второй выводят из стальной трубы, стальную трубу по концам герметизируют и заполняют дистиллированной водой, образец ОК в заполненных дистиллированной водой ЗПТ и стальной трубе помещают в климатическую камеру, через шлюз которой выводят концы образца ОКA method of testing the resistance of an optical cable (OK) to the effect of freezing water, namely, that an OK sample is laid inside a piece of steel pipe so that the ends of the OK exit from the steel pipe, the steel pipe is sealed at the ends and filled with distilled water, then the OK sample is filled with distilled water water, the steel pipe is placed in a climatic chamber, through the lock of which the ends of the OK sample are taken out, a measuring instrument is connected to optical fibers (OV) and their attenuation is controlled, and the temperature in the climatic The measure is changed in accordance with the schedule according to which the OK sample is kept in a steel pipe filled with distilled water at a low negative temperature until the water in the steel pipe completely freezes, the attenuation of the OM during the test is controlled, and it is believed that the OK sample has passed the test if the change in the attenuation of the OM is not exceeds a predetermined threshold value, characterized in that the OK sample is preliminarily laid in a protective polymer pipeline (PST) so that the ends of the OK exit from the PTA, the ends of the PTA seal They are filled and filled with PTA with distilled water, a sample of OK in a filled with water PTA is laid inside a piece of steel pipe so that the ends of the CP come out of the steel pipe, a damping polymer tube is laid next to the PTA in the steel pipe, the first end of which is sealed, and the second end is removed from the steel pipe , the steel pipe at the ends is sealed and filled with distilled water, the sample OK in the filled with distilled water PTA and the steel pipe is placed in a climatic chamber, through the lock of which the ends of the sample OK
