Building the 400G Internet Trends, Technologies, and the Road to 800G+
2020-11-09, 16:30–17:30, Main Stage

In this talk, Andreas (Andy) Bechtolsheim will share his vision for how the 400G and 800G transitions will manifest first in the DC and short haul interconnect build-outs, and then extend to 100-1000km and beyond, all based on next generation digital coherent optical technology.

Advances in DSP and modulation technology make it possible to include 400G, and soon, 800G coherent optical transponders in standard OSFP and QSFP-DD packages that are capable of greater than 1000km transmission over commercially available fiber.

This technology makes it possible to build the next phase of intermediate and long haul Internet backbones with low cost, interoperable, generally available optics that leverage the same technology as short reach optics used in data centers, thus minimizing cost by leveraging economies of scale.

Andreas “Andy” Bechtolsheim is Chairman, Chief Development Officer and Co-Founder of Arista Networks. 
Previously, Andy was a Co-Founder and Chief System Architect at Sun Microsystems, responsible for next generation server, storage, and network architectures.

Andy received a M.S. in Computer Engineering from Carnegie Mellon University in 1976 and was a doctoral student in Computer Engineering at Stanford University from 1977 to 1982. 
 He has been honored with a Fulbright scholarship, the Stanford Entrepreneur Company of the year award, the Smithsonian Leadership Award for Innovation, the EY 2015 US Entrepreneur of the Year Award (together with Jayshree Ullal) and is a member of the National Academy of Engineering.
