400 Gb Ethernet Studie Group

The next generation Ethernet step forward to 400 Gb/s. In March 2013 a IEEE study group (802.3) has been established looking for the technology path to cost-effective 400 Gb/s Ethernet. One method  to increase the number of Bits per symbol is  to use PAM instead of NRZ. An other attractive method is use multiple electrical channels (multi tone) technology.
