This article is about the standards working group. For Ethernet frame data format, see Ethernet frame. IEEE 802.3 is a working group and a collection of IEEE standards produced by the working group defining the physical layer and data link layer 's media access control (MAC) of wired Ethernet.This is generally a local area network technology with some wide area network applications.his amendment to IEEE Std 802.3 defines the physical layer specifications and management parameters for EPON operation on point-to-multipoint passive optical networks supporting extended power budget classes of PX30, PX40, PRX40, and PR40 PMDs.
