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.
