nbn, the company building and operating Australia’s national broadband network, has selected the Coriant CloudWave Optics solution to upgrade its existing nationwide optical transport backbone network in response to growing demand for broadband network capacity.
The nbn transcontinental optical transport backbone (known as the Transit Network) spans over 60,000 kilometers of fiber and is built upon the Coriant hiT 7300 Packet Optical Transport Platform.
The Transit Network allows nbn to connect the different nbn Multi Technology Mix access nodes to points where the traffic is transferred to service providers, known as Point of Interconnect (POI). The access nodes are the modern equivalent of a local telephone exchange and can be located many thousands of kilometers from their corresponding POI, of which there are 121.
Coriant claims that the introduction of Coriant CloudWave Optics which supports software programmable high-speed throughput (100G/150G/200G), within the existing hiT 7300 network will enable nbn to improve utilization of existing fiber resources by over 50% and increase capacity up to 45 Tbps per fiber link, while reducing CapEx and OpEx via reduced footprint, lower power consumption, and improved throughput density.
Deployment of the Coriant flexi-rate solution, which is scheduled to begin in 2017, will target high-traffic routes within the nationwide nbn backbone network.

Maximizing the performance of our fiber optic infrastructure is critical as we expand the capacity of the nbn network throughout Australia and enable residential and business customers to take full advantage of fast and reliable broadband.

Keeping pace with end-user traffic demands while lower operating costs is a challenge shared by network operators and cloud providers around the world.
