Safety for your cable network

With the specially designed and patented optical water sensor, Wolf Kabeltechnik GmbH makes it possible for you to protect your optical cable network from faults caused by water.

Water sensor applications:

in underground joint boxes     WO44 water sensor wave lenght 1550 nm or 1625nm
in joint boxes in buildings     WO45 Fibre optic warning system

Leaking ducts or cable sheaths carry the risk of high follow-up costs. This is one reason why it is important to have certified evidence (with test report) of duct and cable tightness before duct installation, before and after cable-laying and during operation.     WO51 measuring system for monitoring tightness
