Adtran completed a field trial of 800 Gbit/s single-carrier transport, achieving error-free transmission over a record distance of 2,220km in NYSERNet’s production network.
The test route passed through 14 route-and-select flexgrid ROADMs comprising a total of 28 wavelength-selective switches.
The trial used Adtran’s FSP 3000 open line system (OLS), which provided the necessary flexibility to configure the wider required bandwidth and perform testing. It also utilized Acacia’s CIM 8 transceiver technology, which increases baud rates up to 140Gbd to generate 800Gbit/s signals.
“We’ve taken single-carrier 800Gbit/s data transmission further than ever before. And we’ve achieved it not in a lab but in a real-world network also carrying live traffic. What’s more, we succeeded without any optimization to the line system, maintaining the same amplifier settings used before the field trial. We’ve demonstrated that the highest capacity and reach can now be accomplished even over deployed fiber comprising a mix of standard G.652 and G.655 and including multiple network nodes and flexgrid ROADMs,” said Sorin Tibuleac, director of system architecture at Optical Networks, Adtran.
