Copper Network Rehabilitation


DexGreen offers a complete range of legacy copper network components that have been proven in many networks.

Step 1 – Network Assessment and Re-make Damaged, Faulty Cable

  • Audit the network and evaluate network component condition.
  • Sub-standard / damaged components are a leading cause of faults in the network.
  • Moisture ingress is a leading cause of faults (peaking and repeat).
  • Ultimately this leads to network degradation over time when copper pairs are not sufficiently protected.
  • Re-make damaged cable – to ensure copper pairs are in good condition prior to maintenance.

Step 2 – Seal all legacy closures

  • Multiple cable entry ports and damaged sealing result in moisture ingress in legacy closures.
  • Dexgreen has a wide range of quick setting, fit-for-purpose resin sealants that are perfect for sealing the majority of legacy closures.
  • Once sealant has set, insert silica gel into closure in order to absorb moisture and then work on replacing other defective components.
  • Further to this, small pair counts can be accommodated by compact 2 pair / 5 pair / 10 pair gel-filled closures, which are validated to endure harsh environments.

Step 3 – Replace all defective components

  • Corroded / damaged connectors in legacy closures will cause faults and are directly responsible for poor transmission.
  • Once closures are sealed – regenerate copper plant by replacing defective components with approved network components.
  • Dexgreen produces a wide range of fit-for-purpose components that are perfect for the maintenance of copper pairs. These include discrete connectors, accessories such as silica gel, O-rings, etc.
  • Test points are available on all components to ensure testing can be performed quickly and efficiently.

Step 4 – re-entry into the Closure Network

  • Once maintenance activity is complete, test the network to ensure maintenance intervention has yielded satisfactory result. Dexgreen manufactures test equipment that is perfect for network testing and monitoring.
  • This provides Baseline of Stability to identify other defective components in the network to be targeted for repair – fault localisation.
  • Further to this it reduces peak fault rates, extends life of network and reduces expensive truck rolls.
  • This is a grind process and needs to be continuously monitored to ensure the network is performing to its optimum efficiency.
