WS-G Optical fiber water detector

For the detection of penetration by water and chemical
mixtures in connecting sleeves in FTTH networks.


Monitoring option:
Dark Fibre Test (inactive) Active Fibre Test



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.


Benefits of water sensors:

  1. Reliable detection of leakage by means of the intermediately spliced fibre ring
  2. Economical monitoring method
  3. Can be simply and quickly retrofitted at any point
  4. Pinpointing of leakage points over distances of more than 80 km, for short or long leak intervals
  5. No interruption of operation: in operation the water detector fulfils the requirements of standards DIN EN 60793-2-50 and IEC 86A/1343/CD:2010
  6. No activation for a relative humidity under 70%
  7. Prevents fibre breakage. Savings on costs due to repairs and network breakdown.
  8. Depending on the type of monitoring system, star or ring-shaped monitoring of an optical fibre route can be carried out from a central installation by means of optical switches.
