Infinera and Telia Carrier have achieved real-time transmission of 600Gbps on a wavelength in a live production network.

The trial achieved 600G single-wavelength transmission from Palo Alto to San Francisco across Telia Carrier’s production network, which is built on Infinera’s FlexILS platform.

Mattias Fridström, chief evangelist at Telia Carrier, said: “Infinera’s 600G technology can be readily deployed across our existing FlexILS networks, helping us to increase fibre capacity while satisfying our customers’ growing capacity requirements.”

The companies said that the trial illustrates that Telia Carrier’s deployed network is ready for next-generation transponders operating at 600Gbps and beyond, enabling Telia to continue scaling capacity to meet customer demand for the foreseeable future.

“We are pleased to partner with Infinera to yet again demonstrate industry-leading innovation,” said Fridström. “Working together, our companies have a strong history of optical performance leadership, stretching back to the world’s first terabit super-channel trial almost seven years ago.”

The trial used the latest generation of the Infinera Infinite Capacity Engine, ICE5. The technology uses 64 QAM (quadrature amplitude modulation) and 69 gigabaud operation.

Infinera said it sets the foundation for the next generation, ICE6, which is on track to deliver 800Gbps. “Infinera continues to deliver optical engine innovation on a rapid cadence,” said Parthi Kandappan, chief technical officer at Infinera.

“Our ICE4 optical engines are delivering industry-leading performance in deployed networks from metro data centre interconnect to subsea, and this 600G trial showcases the next step function in ICE performance, leading toward 800G wavelengths and beyond in the future.”

Infinera said it plans to deliver commercial products capable of 600Gbps per wavelength in early 2019. In September Infinera announced speeds of 6.2b/s/Hz in a trial with the MAREA subsea cable, and in March it announced an optical device working at 2.4Tbps
