Vodafone Australia required a major Synchronised Digital Hierarchy (SDH) fibre network upgrade throughout Australia’s capital cities to support demand for increased mobile capacity.
The project involved upgrading the network from 2.5 Gbits/s to 10 Gbits/s rings in Sydney, Melbourne, Perth and Adelaide; drafting an intricate and detailed design for installing high capacity nodes, and integrating them into the live SDH fibre network. Kordia provided a turnkey solution, from logistics and detailed design through to installation, commissioning and testing of new equipment.
Kordia was selected due to its excellent knowledge of the Vodafone network, its nationwide engineering support and the synergies between this project and expertise of its other Vodafone transmission capacity projects. Upgrading the live network involved careful manipulation of circuits and concurrent traffic migration to ensure connectivity is maintained between the fibre rings and the network. Timing was absolutely crucial to ensure there was no disruption to the network.
In some cases, Kordia had to re-use Vodafone’s existing dark fibre, which meant that the team had to migrate traffic and rearrange parts of network to free up dark fibre segments that were later used to setup the new 10Gbits/s rings.
Kordia experts rose to the challenge, completing traffic migrations and network re-arrangements with ease without the drop of a single call.
