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.’

EXFO solutions test up to 800GbE with ultimate flexibility in lab and field – LTB-12 and FTB-4 Pro test platforms with FTBx-88460 modules, BA-4000 electrical bit-error rate tester and EA-4000 sampling scope
