For the detection of penetration by water and chemical
mixtures in connecting sleeves in FTTH networks.
Water detectors are used to detect leaks. They serve to prevent transmission breakdown in telecommunication facilities, seepage from service or waste water in the earth or ground water pollution due to leakage of chemical substances.
If a leak occurs, the water detectors cause measurable attenuation changes as a result of manufacturer-dependent macrobending loss in the fibre.
Various types of water detectors are available, in accordance with market needs
see Table WO44 part 0: Water detector delivery programme.
