Orange and Coriant demonstrated what they claim to be the highest ever C-band transmission capacity using 16QAM (24Tbps) and 64QAM (38.4Tbps) modulation in a live network environment.
The trial was conducted over a live fibre link in Orange’s transport infrastructure between Lyon and Marseille, France, and was completed in cooperation with the SASER (Safe and Secure European Routing) project.
“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,” said Uwe Fischer, CTO at Coriant.
“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.”
Coriant’s field trial with TSIC featured the successful transmission of three different software-programmable modulation formats – QPSK, 8QAM and 16QAM – over a distance of 1,634km each.
The trial took place on a fibre-optic route between Paris, Luxembourg and Frankfurt, and demonstrated line-side transmission speeds of 100G, 200G, 300G and 400G.
“Staying ahead of the customers’ ever increasing connectivity needs are paramount for us,” said Mattias Fridström, VP and head of technology at TSIC.
“This 400G field trial is all about ensuring the flexibility at all layers of the network, and especially in the underlying high-capacity transport infrastructure required for delivering the best high performance connectivity for our customers and their end-users.”
In July last year, Coriant teamed up with Allied Fiber for the successful demonstration of 1Tbp super-channel transmission in Florida, US.
