This amendment to IEEE Std 802.3-2012 adds Physical Layer (PHY)
specifications and management parameters for 40 Gb/s operation over
single-mode fiber (40GBASE-ER4) and for 100 Gb/s operation over
multimode fiber (100GBASE-SR4). This amendment also specifies a
four-lane variant of the 100 Gigabit Attachment Unit Interface
(CAUI-4) and optional Energy Efficient Ethernet (EEE) for 40 Gb/s
and 100 Gb/s operation over fiber optic cables.
