The test route passed through 14 route-and-select flexgrid ROADMs comprising a total of 28 wavelength-selective switches. Leveraging 140GBd digital signal processing (DSP) technology from Acacia, an industry leader for silicon-based high-speed optical interconnect products, this result was made possible by Adtran’s use of continuous symbol rate tuning and probabilistic constellation shaping offered by Acacia’s Coherent Interconnect Module 8 (CIM 8). The trial showcases an opportunity for network operators to increase capacity and efficiency while minimizing complexity and cost.\n\n“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. “Building on the success of our TeraFlex™ CoreChannel™ technology, these results represent the next milestone in the development of high-speed optical networks. The potential to enhance throughput while minimizing opex and operational complexity is immense.”\n\nAdtran’s trial marks the longest distance ever achieved for 800Gbit/s data transport using a single optical carrier with real-time DSP. To realize this, it utilized Acacia’s CIM 8 transceiver technology, which increases baud rates up to 140Gbd to generate 800Gbit/s signals. By achiev...
