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.
The introduction of Coriant CloudWave™ Optics technology within the existing hiT 7300 network will provide nbn the ability to leverage the industry’s latest advances in high-speed, low latency optical networking, including per-wavelength transmission at speeds of 200G and beyond.
Coriant CloudWave™ Optics is an innovative coherent optical transmission solution that supports software programmable high-speed throughput (100G/150G/200G) to lower cost per bit as networks scale. The flexible and highly compact line side interface solution 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.
“Coriant’s CloudWave™ solution will help us in scaling the nbn and connecting 8 million happy homes by 2020. 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,” said Peter Ryan, Chief Network Engineering Officer at nbn.
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.
“Keeping pace with end-user traffic demands while lower operating costs is a challenge shared by network operators and cloud providers around the world,” said Petri Markkanen, Managing
Director, Asia Pacific, Coriant. “Our CloudWave Optics solution provides these operators a powerful toolkit to seamlessly scale to higher speeds while delivering proven ROI through lower power, reduced space, and improved reach performance.”
