40 Gigabit Ethernet (40GbE) and 100 Gigabit Ethernet (100GbE) are groups of computer networking technologies for transmitting Ethernet frames at rates of 40 and 100 gigabits per second (Gbit/s), respectively.
By convention, bus and network data rates are denoted either in bits per second (bit/s) or bytes per second (B/s).In general, parallel interfaces are quoted in B/s and serial in bit/s.
Supermicro AOC-SGP-I2 dual-port Gigabit Ethernet NIC, a PCI Express ×4 card. 1000BASE-T (also known as IEEE 802.3ab) is a standard for Gigabit Ethernet over twisted-pair wiring. Each 1000BASE-T network segment is recommended to be a maximum length of 100 meters (330 feet), [5] [a] and must use Category 5 cable or better (including Cat 5e and ...
3Com 3C905B-TX 100BASE-TX PCI network interface card. 100BASE-TX is the predominant form of Fast Ethernet, and runs over two pairs of wire inside a Category 5 or above cable. Cable distance between nodes can be up to 100 metres (328 ft). One pair is used for each direction, providing full-duplex operation at 100 Mbit/s in each direction.

Generally, layers are named by their specifications: [8] 10, 100, 1000, 10G, ... – the nominal, usable speed at the top of the physical layer (no suffix = megabit/s, G = gigabit/s), excluding line codes but including other physical layer overhead (preamble, SFD, IPG); some WAN PHYs (W) run at slightly reduced bitrates for compatibility reasons; encoded PHY sublayers usually run at higher ...
[12] 802.3ba-2010 defines 40 Gigabit Ethernet over this connection as "40GBASE-CR4" and a 100 Gigabit connection over three of these connections named 100GBASE-CR10 (now in phase out). SFP28, which runs at 28 Gbps for 25 Gigabit Ethernet (25GBASE-CR1), was defined in 2014; a quad version (QSFP28) capable of running 100 Gbps was also defined. [ 13 ]
NDI is designed to run over gigabit Ethernet [1] with the NDI codec. [2] It delivers 1080i high-definition video at variable data rates typically around 100 Mbit/s. [3] By default, NDI uses multicast DNS to advertise sources on a local area network, such that NDI receivers can
