A new task force with the Institute of Electrical and Electronic Engineers ( IEEE ) on project 802.3cm was formed in March 2018 to fulfil two new multimode objectives for 400 Gb/s Ethernet operation:
400GBASE-SR8 – an 8-pair, 1-wavelength multimode solution supporting reaches of 70/100/100 m over OM3/4/5 400GBASE-SR4.2 – a 4-pair, 2-wavelength multimode solution supporting reaches of 70/100/150 m over OM3/4/5 400GBASE-SR8 is the first IEEE fiber interface to use eight pairs of fibers.
