Of the Fast Ethernet physical layers, 100BASE-TX is by far the most common. Fast Ethernet was introduced in 1995 as the IEEE 802.3u standard [1] and remained the fastest version of Ethernet for three years before the introduction of Gigabit Ethernet. [2] The acronym GE/FE is sometimes used for devices supporting both standards. [3]

Autonegotiation is the procedure by which two connected devices choose common transmission parameters, e.g. speed and duplex mode. Autonegotiation was initially an optional feature, first introduced with 100BASE-TX (1995 IEEE 802.3u Fast Ethernet standard), and is backward compatible with 10BASE-T.
Terabit Ethernet (TbE) is Ethernet with speeds above 100 Gigabit Ethernet. The 400 Gigabit Ethernet ( 400G , 400GbE ) and 200 Gigabit Ethernet ( 200G , 200GbE ) [ 1 ] standard developed by the IEEE P802.3bs Task Force using broadly similar technology to 100 Gigabit Ethernet [ 2 ] [ 3 ] was approved on December 6, 2017.
IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet.The standards are produced by the working group of the Institute of Electrical and Electronics Engineers (IEEE).
Cisco Systems and Comcast announced their 100GbE trials in June 2008. [72] However, it is doubtful that this transmission could approach 100 Gbit/s speeds when using a 40 Gbit/s per slot CRS-1 platform for packet processing. Cisco's first deployment of 100GbE at AT&T and Comcast took place in April 2011. [73]
The physical coding sublayer (PCS) is a networking protocol sublayer in the Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet standards. It resides at the top of the physical layer (PHY), and provides an interface between the physical medium attachment (PMA) sublayer and the media-independent interface (MII).
