Infinera and Arelion (formerly Telia Carrier) announced a record-setting transmission of 400 Gb/s using a QSFP-DD pluggable coherent transceiver over 1,800 km of SMF-28 fiber in a live production network.
The result was achieved using Infinera’s ICE-X 400G ZR+ intelligent pluggable coherent transceiver across Arelion’s production transmission network on routes between Dallas, Memphis, and Chattanooga.
The field trial also demonstrated the programmability of Infinera’s ICE-X intelligent pluggable coherent solution. By adjusting the modulation of the optical signal in the same pluggable coherent solution, the companies also demonstrated long-distance performance at 300 Gb/s and 200 Gb/s using a QSFP-DD pluggable. These achievements were made possible by leveraging Arelion’s open and disaggregated networking approach over its live network with concurrently deployed wavelengths, including those of third-party solution providers.
“We are pleased to once again partner with Infinera,” said Georgios Tologlou, Senior Network Architect at Arelion. “We were early investors in optical pluggable components to drive demonstrable value and cost-efficiency for our customers. Lab trials with perfect fiber are one thing. But we are not afraid to test these pluggables in live networks over the same fiber we’re using for live traffic, so we were happy to demonstrate the real-world potential of Infinera’s new coherent pluggable technology when implemented through Arelion’s open and disaggregated network architecture.”
