Coriant announced that Australia-based NBN has started the deployment of CloudWave Optics technology across its 60,000 kilometer optical transport backbone network.

The US-based networking solutions company said that the investment in network upgrade enables NBN to double bandwidth capacity with coherent optical technology that supports per-wavelength transmission rates of 200 Gbps.

Coriant CloudWave Optics coherent interface solution supports software programmable high-speed transmission to lower cost per bit as networks scale. The upgrade to CloudWave Optics will allow NBN Co to increase maximum capacity on its transit network from 9.6 Tbps to 19.2 Tbps per fiber link.

Reduction in capital and operating expense due to smaller footprint requirements, reduced power consumption, and greater throughput density are the main benefits from the deployment of Coriant solutions, said Alfred Ling, managing director, North Asia & Oceania, Coriant.

The innovative technology supports seamless upgrade to 400G. Initial upgrade sites span high-traffic fiber links between Eastern Creek and Asquith in Sydney and the 3,600 km route between Brisbane, Queensland, and Darwin in the Northern Territory.

“This upgrade will ensure we can continue to deliver a reliable and high-quality broadband access network for nur wholesale customers even as high-bandwidth applications and the growth of internet usage continue to drive demand for network capacity,” Kathrine Dyer, chief network deployment officer of NBN, said.

NBN’s backbone network – known as the Transit Network – was built using the Coriant hiT 7300 Multi-Haul Transport Transport Platform and spans over 60,000 kilometers of fiber around Australia to connect access nodes to NBN’s 121 Points of Interconnect (POI) where traffic is transferred to service providers.
