This document summarizes a presentation on 40 GbE and 100GbE technologies. It discusses the state of 40GbE and 100GbE physical layer specifications and form factors. It also looks ahead to growing the 40GbE/100GbE family and the industry technology roadmap, including developments in backplanes, cabling, optics and modules. Key initiatives are highlighted like new IEEE study groups on backplanes/cabling and assessing future Ethernet bandwidth needs.
