Infinera (NASDAQ: INFN) and Corning Inc. (NYSE: GLW) say they have combined to transmit an 800G wavelength 800 km. The demonstration leveraged Infinera’s sixth-generation Infinite Capacity Engine (ICE6) and Corning’s TXF optical fiber.

The ICE6 was housed in an Infinera Groove (GX) Series platform. Infinera announced the ICE6 last year just before OFC 2019 (see “Infinera unveils ICE6 coherent engine, Infinite Network vision”). The coherent engine is based on the company's FlexCoherent digital signal processor and leverages 7-nm silicon technology as well as per-subcarrier long-codeword probabilistic constellation shaping (PCS), Nyquist subcarriers, and per-subcarrier dynamic bandwidth allocation.

TXF fiber is an ITU-T G.654.E compliant, ultra-low-loss, silica-core fiber with large effective area.

“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 fiber,” 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 maximize capacity and reach,” said Jeanne Propst, division vice president, product line management, Optical Fiber and Cable, Corning Inc. “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.”
