According to Infinera, the trial demonstrated XR optics' compatibility within the NBN transit network, and showed it could simplify transport network architecture while reducing capital and operating expenses.
XR optics is said to provide multiple 100Gbps of capacity divided into discrete subcarriers, allowing dynamic capacity management and optical capacity optimisation.
"The NBN transit network is our national backbone, supporting the growing data needs of Australians as they rely more on broadband for their work, education, social and entertainment needs," said NBN Co CTO Ray Owen.
"It is important that we keep track of new innovations to guide how we evolve our network to help meet changing needs in the future. Working with Infinera helps us to understand the options and design our pathways accordingly."
Infinera co-founder and chief innovation officer Dave Welch said "This trial with NBN Co provides a proof point illustrating how Infinera's digital subcarrier-powered XR optics can be seamlessly integrated into existing networks and successfully applied in a variety of network applications from backhaul networks to data centre interconnect.
"The XR optics trials Infinera has conducted continue to represent a radical shift in the way future networks can be built, promising a dramatic reduction in TCO, helping to set a new benchmark in scalability, and increasing service flexibility and velocity."
