Keeping Water out of Network

The diagram below illustrates the most vulnerable parts of the access network and reliable solutions that Dexgreen offers to reliably seal the network. Each of these products meet relevant design standards and are backed up with testimonials from carriers such as BT, Eircom and Telstra.Slide1Issue: In copper networks, a significant location of faults is where cables are joined / interfaced as a result of moisture ingress.

Therefore it is essential that all copper access network components are carefully designed to operate under water (when sealed to the appropriate quality standard).

If performed correctly – weather events will not cause a significant increase in faults (with the exception of direct lightning strikes or extreme flooding, both of which cause extreme physical damage to all types of infrastructure).

Therefore when faults are identified after significant rainfall, it means that the network is not adequately sealed. Key reasons for this are:

  • Natural deterioration / network fatigue over time; or
  • Poor Quality standards and maintenance


Solution: To reduce faults effectively – a targeted Fault Volume Reduction (FVR) programme must be enforced, where every network intervention by engineers (through provision or maintenance) ensures that the network meets the appropriate quality standard.
