IEEE 802.3bm-2015 PDF
This standard defines Ethernet local area, access and metropolitan area networks. Ethernet is specified at selected speeds of operation; and uses a common media access control (MAC) specification and management information base (MIB). The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full duplex operation. Speed specific Media Independent Interfaces (MIIs) provide an architectural and optional implementation interface to selected Physical Layer entities (PHY). The Physical Layer encodes frames for transmission and decodes received frames with the modulation specified for the speed of operation, transmission medium and supported link length. Other specified capabilities include: control and management protocols, and the provision of power over selected twisted pair PHY types.
Amendment Standard – Superseded. Physical Layer 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) are added by this amendment. 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.
