Optical fiber water detectors for detecting leaks in fibre optic junction boxes

The purpose of fiber-optic water detectors is to detect leaks. They help to prevent transmission failure in telecommunication installations, seepage of waste water or sewage into the soil, and groundwater contamination caused by leaking chemicals. If a leak occurs, the fiber-optic water sensors generate measurable attenuation change as a result of (manufacturer-dependent) macro bending loss in the optical fibers.

Water detectors for detecting leaks

Welcome to our page for fibre-optic water detectors – your first line of defence against leaks! Our innovative fibre-optic water detectors are specially designed to reliably identify leaks in telecommunication installations and thus prevent system breakdowns. They also guard against seepage of waste water or sewage into the soil and prevent groundwater contamination caused by leaking chemicals..

Fibre-optic water detectors: Our water detectors are available in two versions, to suit different optical fiber requirements.

44.1 WS-B/K1:

  • ​​​​​Ideal for bend-resistant fibers such as G.657.A1/A2 and G.657.B2/B3.
  • If a leak occurs, the sensors generate measurable attenuation change as a result of macro bending loss in the optical fibers.

44.2 WS-G:

  • Designed for bend-sensitive fibers such as G.652.D and G.657.A.
  • These water detectors enable precise leak detection, to safeguard your network from damage

Our fiber optic water sensor uses advanced technology to give you early warning of possible leakage. This will not only minimise the downtime caused by breakdown, but will also protect your network from serious damage due to water, chemicals or other potential hazards.

You can trust our water sensors to safeguard your telecommunications network or your infrastructure. Invest in early leakage detection and ensure that your network is always in tip-top shape.
