Kandou Bus announced today that David Stauffer of Kandou will speak at the OFC Market Watch session entitled OIF CEI 56G: Signal Integrity to the Forefront. Dr. Stauffer serves as the Chair of the Physical and Link Layer (PLL) Working Group of the Optical Internetworking Forum (OIF) and is a lead design engineer for Kandou Bus with more than 30 years of experience at Kandou and IBM. He will speak with three other OIF leaders in a panel discussing the development of the new OIF CEI-56G specifications on Tuesday, March 22 at 10:30- 11:30 AM in Expo Theater II, Exhibit Hall B of the Anaheim Convention Centre.

PAM-4 has been shown to be fragile, needing heavy FEC even for shorter links, said Amin Shokrollahi, Kandou Founder and CEO. Ensemble NRZ (ENRZ) modulation is much more robust and has been shown to support a wide range of link profiles, both short- and long-reach, without requiring Forward Error Correction (FEC) because it makes optimal use of the spatial diversity that is provided by four-wire links. The core of Kandou’s innovative technology is a novel vector signaling technology called Chord™ signaling in which correlated signals are sent across more than two wires. ENRZ is a version of Chord signaling that sends 3 bits over 4 correlated wires with inherently better signal integrity than PAM4. As a result, FEC can be substantially simplified and in many cases eliminated altogether, enabling lower power and more robust system solutions.

Kandou has also released its Glassing™ transceiver that uses another version of Kandou’s Chord signaling optimized for in-package use.
