Infinera Tests Some Long Distance 400G With Arelion, Corning

March 7th, 2023 by · Leave a Comment

Infinera revealed a couple of interesting trials yesterday. They went after the longhaul, both in the field with Arelion and in the lab with Corning. They have been stretching the reach of their 400G wavelength technology, leveraging their ICE-X pluggable solution.

Arelion and Infinera revealed a record-setting trasmission of 400Gbps wavelengths of 1,800km over a live production network with deployed, 3rd party wavelengths. The trial used QSFP-DD pluggable coherent tranceivers and sent data over SMF-28 fiber. The path was in Arelion’s North American network between Dallas, Memphis, and Chattanooga. They also tested 300Gbps and 200Gbps configurations.

Meanwhile, Corning and Infinera took to more pristine conditions to reach 2,400km. Using the same ICE-X pluggables but over Corning’s TXF optical fiber and using UfiSpace’s disaggregated routing technology. With all the new fiber folks are putting in place out there, whether pulling through existing conduits or in newly dug trenches, that kind of performance will certainly raise an eyebrow or two.
