800G achieved on single wavelength with company collaboration

Share this on social media:

Infinera and Corning have teamed up to achieve an 800G single wavelength. This was accomplished with Infinera’s sixth-generation Infinite Capacity Engine (ICE6) technology across 800km on Corning’s TXF optical fibre.

The success of the companies’ trial demonstrates the benefits of a coherent 800G solution with fibre that is designed to help meet growing bandwidth demands for network operators from metro to subsea network applications.

The demonstration leveraged Infinera’s ICE6 technology – including Nyquist subcarriers, per-subcarrier long-codeword PCS, and per-subcarrier dynamic bandwidth allocation – in a Groove (GX) Series platform, transmitting 800G using 64QAM with probabilistic constellation shaping (PCS). It was accomplished using Corning’s TXF fibre, an ITU-T G.654.E compliant, ultra-low-loss, silica-core fibre with large effective area.

Parthi Kandappan, chief technology officer at Infinera commented: ‘This demonstration proves 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 fibre. 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 holistic in-house packaging.’

Added Jeanne Propst, division vice president, product line management, optical fibre and cable, Corning Incorporated: ‘We are pleased to work with Infinera to demonstrate how our combined leading-edge technologies can maximise capacity and reach. Our TXF fibre, with its high-data-rate capabilities and exceptional reach, helps network operators stay ahead of growing bandwidth demands while lowering their overall network costs.’
