Infinera And Corning Achieve 800G Across 800km

News

Sixth-generation Infinite Capacity Engine can meet growing bandwidth demands for network operators

Infinera has delivered 800 gigabits per second (800G) single wavelength with its sixth-generation Infinite Capacity Engine (ICE6) technology across 800 km on Corning's TXF optical fibre. The success of Infinera and Corning's 800G trial demonstrates the benefits of an industry leading coherent 800G solution with superior fibre designed to help meet growing bandwidth demands for network operators from metro to subsea network applications.

The demonstration used 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 fibre, an ITU-T G.654.E compliant, ultra-low-loss, silica-core fibre with large effective area. This demonstration highlighted the advanced features of Infinera's vertically integrated ICE6 technology, including Nyquist subcarriers, per-subcarrier long-codeword PCS, and per-subcarrier dynamic bandwidth allocation.

“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,” said Parthi Kandappan, CTO at Infinera. “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.”

“We are pleased to work with Infinera to demonstrate how our combined leading-edge technologies can maximise capacity and reach,” said Jeanne Propst, division vice president, product line management, Optical fibre and Cable, Corning Incorporated. “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.”

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.

Following on from the successful launch of the virtual AngelTech Online Summit in May 2020, we are delighted to announce AngelTech Live II, taking place on 2 November 2020. AngelTech will once again consist of our established events of CS International and PIC International.

The 2nd virtual summit will utilise an enhanced event engine, integrating presentations, digital sponsors booths and the networking tools into one portal – allowing for live chat between delegates, speakers and sponsors.

The event will take the form of three interactive sessions over 1 day and will be a must attend live summit consisting of:

  • Analyst talks
  • Industrial research
  • End user presentations
  • Dedicated breakout room for partner presentations
