NBN deploys Infinera SDN solution across fiber optic transit network

Infinera announced that NBN, a wholesale broadband provider in Australia, installed self-healing capabilities into its transit network with the deployment of Infinera’s Transcend software-defined networking (SDN) solution.

Infinera’s SDN-based dynamic service rerouting capabilities for dense wavelength-division multiplexing (DWDM)-based networks allow network operators to restore customer services by automatically rerouting traffic when faults occur.

NBN will deploy the solution across its 60,000-kilometer fiber optic transit network. NBN’s transit network is a backbone network of fiber optic cables that links hubs across Australia to the wider nbn broadband access network that connects homes and businesses. This network moves large aggregate volumes of data between locations, delivering capacity to homes and businesses.

The network connects to NBN’s 121 points of interconnection (POIs) – typically located at telephone exchanges – which are where phone and internet providers plug their own networks into the NBN Co access network.

The reconfigurable optical add-drop multiplexer (ROADM) technology enhancements introduced on the Infinera 7300 Series Multi-Haul Transport Platform will allow NBN Co to increase its network resiliency and reliability by introducing automatic service restoration capabilities across its transit network.

“The Transcend SDN solution was deployed and integrated with our systems, giving us the capability to increase service availability to some of the most remote locations across Australia,” said Kathrine Dyer, chief network deployment officer at NBN.
