[6] The Optical Internetworking Forum (OIF) has already announced five new projects at 112 Gbit/s which would also make 4th generation (single-lane) 100 GbE links possible.
[2][11] Accordingly, at the IEEE Industry Connections Higher Speed Ethernet Consensus group meeting in September 2012, 400 GbE was chosen as the next generation goal.
The University of California, Santa Barbara (UCSB) attracted help from Agilent Technologies, Google, Intel, Rockwell Collins, and Verizon Communications to help with research into next generation Ethernet.
[12] As of early 2016, chassis/modular based core router platforms from Cisco, Juniper and other major manufacturers support 400 Gbit/s full duplex data rates per slot.
[15] 200G Ethernet uses PAM4 signaling which allows 2 bits to be transmitted per clock cycle, but at a higher implementation cost.
Subsequently, the IEEE 802.3bs Task Force[23] started working to provide physical layer specifications for several link distances.
