Abstract: Изобретение касается волоконно-оптического кабеля, который является устойчивым к радиальному проникновению и к продольному распространению воды. Кабель содержит растворимый в воде полимерный материал, способный разбухать под действием воды. При поступлении воды в этот кабель распространение воды блокируется за счет объединенного эффекта набухания растворимого в воде материала и образования водного раствора упомянутого материала, который имеет предварительно определенную вязкость, для препятствования протеканию остаточной воды. Растворимый в воде материал предпочтительно выбирают из полиакриламида, модифицированного поливинилового спирта, сополимеров винилового спирта/винилацетата, поливинилпирролидона и их смесей, причем материал предпочтительно является сополимером винилового спирта/винилацетата. Материал можно экструдировать, чтобы образовать трубчатые элементы для охватывания оптических волокон, например двухслойные трубчатые элементы, в которых внутренний слой сделан из растворимого в воде материала, а наружный слой сделан из обычного полимера типа ПЭ, ПП или ПБТ. 3 с. и 31 з.п.ф-лы, 5 ил., 7 табл.
