Infinera and Corning push 800 gigabits down optical fibre

Single wavelength across 800 kilomenters 

Infinera and Corning deliver 800 gigabits per second (800G) single wavelength with Infinera’s sixth-generation Infinite Capacity Engine (ICE6) technology across 800 kilometers (km) on Corning’s TXF optical fibre.

The companies say the success of Infinera and Corning’s 800G trial demonstrates the benefits of a coherent 800G solution with superior fibre designed to help meet growing bandwidth demands for network operators from metro to subsea network applications.

The demonstration leveraged Infinera’s ICE6 technology in a Groove (GX) Series platform transmitting 800G using 64QAM with probabilistic constellation shaping (PCS). This record-breaking achievement was accomplished using Corning’s state-of-the-art TXF fiber, an ITU-T G.654.E compliant, ultra-low-loss, silica-core fibre with large effective area.

The demo was to show off Infinera’s vertically integrated ICE6 technology, including Nyquist subcarriers, per-subcarrier long-codeword PCS, and per-subcarrier dynamic bandwidth allocation.

Infinera CTO Parthi Kandappan said that the demo proved that 800G transmission using Infinera’s industry-leading technology enables a wide variety of network applications and is further enhanced by Corning’s innovative TXF fiber. “This achievement is made possible by Infinera’s high degree of vertical integration including our in-house digital signal processor design, photonic integrated circuit design and manufacturing, and in-house packaging..”

Jeanne Propst, division vice president, product line management, Optical Fibre and Cable, Corning Incorporated, said: “Our TXF fiber, with its high-data-rate capabilities and exceptional reach, helps network operators stay ahead of growing bandwidth demands while lowering their overall network costs.”

ICE6 combines Infinera’s sixth-generation photonic integrated circuit with its in-house-developed 7-nanometer dual-channel 800G per-wave FlexCoherent digital signal processor.
