Orange has partnered Coriant to conduct a multi-terabit field trial, showcasing the latest advances in ultra-high-capacity optical communications technologies. The field trial, part of an ongoing technology collaboration, was conducted across a live G.652 fiber link in the Orange transport infrastructure connecting the cities of Lyon and Marseille in France.
In this record-breaking field trial, advanced technology researchers from Coriant and Orange successfully demonstrated the highest ever C-band transmission capacity using 16QAM (24 Tbps) and 64QAM (38.4 Tbps) modulation formats in a live networking environment. Both companies claim that they have also achieved a record-setting transmission reach of 762 kilometers using 32QAM modulation (32 Tbps) and 64QAM (38.4Tbps) in the same live environment, more than twice the distance of any previous field records for 32QAM, and the first ever regional transmission for 64QAM.
According to Coriant, the error-free super-channel transmission speeds and distances were achieved using advanced high-order modulation techniques, next-generation Digital Signal Processing (DSP) algorithms and Forward Error Correction (FEC) codes developed by Coriant, its advanced optical system features, and Coriant’s next-generation flexi-rate prototype technologies.
Coriant added that the trial, which took place in May, also marked the first ever demonstration of terabit super-channel transmission across a live network in France, as well as the first ever field demonstration of full flexi-rate and flexi-grid transmission – ranging from QPSK to 64QAM.

Innovative technologies such as software-programmable flexi-rate, flexi-grid, and super-channels will become increasingly important as demand for more agile and scalable optical transport networks continues to grow. Our collaboration with Orange in the SASER Project with all the SASER partners has played an important role in advancing the state of research in these key technologies, while laying the groundwork for continued innovation in Coriant’s current and future product portfolio, including our CloudWave-enabled 400G flexi-rate offering.
