NBN Co trials "super-channel" transmission with Coriant

"This proof point highlights that the existing transit network is robust and capable, as we rollout a mixture of Fibre-to-the- node technologies (FTTx) being designed to provide access to voice and broadband services faster, cheaper and more efficiently to Australian homes and businesses no matter their location across the country.

"As high-bandwidth applications and the growth of internet usage drive increased demand for network capacity, the ease of upgrading to higher transmission rates in our Transit Network will enable us to continue to deliver a reliable and high-quality broadband experience for our customers."

Using commercial-grade Coriant hiT 7300 DWDM system hardware, including Flexi-grid technology, the trial demonstrated NBN Co's ability to efficiently scale its network as end-user traffic demands in Australia increase.

According to a company statement, Flexi-Grid technology is based on an adaptive channel grid with wavelengths dynamically selected based on the data rate. By increasing channel density, Flexi-Grid technology enables NBN Co to maximise the use of the existing fibre optic infrastructure, while maintaining network flexibility, resiliency and performance.

Coriant is a strategic supplier of Optical Transmission Equipment and management systems to NBN Co.
