100 Gigabit Ethernet

The next generation of Ethernet. The IEEE 802.3ba committee is developing Ethernet technologies at 40 and 100 gigabits per second to succeed 10 Gigabit Ethernet. With standards ratified in 2010, 40 GbE is designed for use within the organization between servers and the Ethernet switch, and 100 GbE for switch-to-switch transmission (long distance channels).

Multiple Lanes
For 100 GbE, proposed modulation schemes include breaking 100 Gbps into four 25 Gbps data lanes by splitting the 100 into two polarized streams, each of which is modulated into two 25 Gbps streams. See Ethernet.
