100 gigabit Ethernet or 100GbE is an Ethernet standard presently under early development by the IEEE. The fastest existing standard is 10 gigabit Ethernet. In late November 2006, an IEEE study group agreed to target 100Gbps Ethernet as the next version of the technology.

The IEEE 802.3 Higher Speed Study Group (HSSG) has adopted several objectives which direct their current work. These include 100GbE optical fiber Ethernet standards of both at least 100 meters and at least 10 kilometers, full-duplex operation only, and using current frame format and size standards. It is expected that the Study Group will present a Project Authorization Request (PAR) to the 802 Standards Executive Committee in July 2007.

The HSSG study group on November 16 2006 specifically adopted as objectives:

  • Support a speed of 100 Gb/s at the MAC/PLS interface
  • Support at least 100m on OM3 MMF
  • Support at least 10km on SMF
  • Support at least 40km on SMF
  • Support full-duplex operation only
  • Preserve the 802.3 / Ethernet frame format at the MAC Client service interface
  • Preserve minimum and maximum FrameSize of current 802.3 Std
  • Support a BER better than or equal to 10^-12 at the MAC/PLS service interface
