Australia’s wholesale open-access broadband provider, NBN Co, has completed a successful proof of concept trial of Infinera’s XR optics-based point-to-multipoint coherent optical technology.
The trial demonstrated XR optics’ compatibility within the provider’s Transit Network, a DWDM-based network that spans more than 65,000km across Australia. It highlighted the ability of the technology to simplify transport network architecture with the aim of reducing CapEx and OpEx across diverse applications.
Providing multiple 100Gb/s of capacity efficiently subdivided into discrete subcarriers, XR optics is designed to enable capacity management and optimisation. The demonstration was designed to inform how NBN Co considers options to evolve its transport network to support growing data demands in the future.
Ray Owen, chief technology officer at NBN Co commented: ‘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. 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.’
Dave Welch, chief innovation officer and co-founder at Infinera added: ‘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 center interconnect.’
