Telstra has wrapped up the second phase of its ongoing transmission network upgrade, deploying high capacity next generation optical transport technology between Melbourne, Sydney, Brisbane, Adelaide and Perth.

According to the telco, this will provide increased capacity, enhanced resiliency and extensive scalability to cope with the demand on its networks.

The work is part of a three-year upgrade project to expand Telstra’s long haul, metro and regional optical networks, which has already seen the Tasmanian part of the upgrade completed in August.

With the upgrade underway, Telstra can support up to 8.8Tbps between the five major Australian centres, as well as increased capabilities around resilience and software defined networking.

When ready, the upgrade of Telstra’s inter-capital optical network is set to deliver "super speeds", with the system capacity scalable with future developments from 75Tbps to over 100Tbps between capital cities as demand grows.

With redundant optical linkages between the capital cities, Telstra’s backbone network can continue to deliver a service even if some fibre paths are disrupted.

“Our transmission network upgrade is a foundational investment in building the networks for the future to meet the growing demands of our consumer and enterprise customers,” Telstra group managing director networks, Mike Wright, said.

“It enables increased capacity and flexibility, improved resilience, and readiness for new technologies such as 5G, cloud computing and internet of things.”

Wright said the telco is forecasting network traffic five times bigger in five years due to the growth of smart devices, video streaming and cloud computing.

“This transmission upgrade project is about making sure we have the capacity and resiliency to meet these demands,” Wright added.

In August, Telstra said it was rolling out optical transport technology across its transmission network, which was set to increase both capacity and flexibility of the network as well as improve resilience.

“We have lit up the optical transmission technology across the state [Tasmania] and on the cable routes running across Bass Straitm,” said Telstra chief operations officer, Robyn Denholm, at the time.

“The upgrade will increase Telstra’s network capacity on each of Telstra’s two subsea cables running across the Bass Strait from 400 Gigabit to one Terabit per second – the equivalent of 200,000 HD videos being streamed simultaneously (based on a 5Mbps per streamed HD video).

“We will now be progressively upgrading our optical transport capability around Australia, with Victoria, New South Wales and South Australia the next in line to benefit from from inter-capital upgrades,” she added.
