Telstra upgrades network capacity to 40Gbps between Melbourne, Sydney

Growing demand on its network has prompted Australian operator Telstra to upgrade the capacity of the existing Dense Wave Division Multiplexing (DWDM) transmission from 10 to 40 Gbps between Melbourne and Sydney. The company said it is seeing traffic demand double on the network every 19 months.

"The Telstra Next IP network is the backbone for all our networks and our customers, particularly our enterprise and government customers, who have come to rely on its speed and capacity to drive productivity gains within their organisations," Telstra COO Michael Rocca said. "This is the first of our intercapital routes to be upgraded and we expect to carry out similar upgrades to other major cities over the coming year."

The upgrade augmented the existing DWDM system using Ericsson's Marconi MHL 3000 platform and required no changes to the underlying infrastructure. The Marconi platform can deliver up to 80 channels at 40Gbps per channel over a single fiber pair.

"When we announced this upgrade last July we said there was a path to 100Gbps; this continues to be our direction," Rocca said.
