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.
