10BaseT, also known as 10Base-T, is a transmission medium specified by IEEE 802.3i that carries information at rates up to 10Mbps in baseband form using unshielded twisted pair (UTP) conductors with low cost Level 3 or better UTP wiring up to 100 meters (328 ft.). 10BaseT uses RJ45 connectors and sometimes 50-pin AMP connectors to a patch panel.

10GBase is a set of standards as defined by IEEE 802.3ae for Gigabit Ethernet system to operate in full-duplex mode only, over fiber optic media. There are a few media types, which are designed for use in either local or wide-area networking. This provides the 10 Gigabit Ethernet system with the flexibility needed to operate in local area networks (LAN), metropolitan area networks (MAN), regional area networks (RAN) and wide area networks (WAN). IEEE 802.3ae provides support to extend the 802.3 protocol and MAC specification to an operating speed of 10 Gb/s. Several Physical Coding Sublayers known as 10GBASE-X, 10GBASE-R and 10GBASE-W are specified, as well as significant additional supporting material for a 10 Gigabit Media Independent Interface (XGMII), a 10 Gigabit Attachment Unit Interface (XAUI), a 10 Gigabit Sixteen-Bit Interface (XSBI) and management.
The 10GBase includes 10GBASE-S, a 850nm wavelength serial transceiver which uses two multimode fibers; 10GBASE-L4, a 1310nm wavelength division multiplexing (WDM) transceiver which uses two multi-mode or single mode fibers; 10GBASE-L, a 1310nm wavelength serial transceiver which uses two single mode fibers; and 10GBASE-E, a 1550nm wavelength serial transceiver which uses two single mode fibers.

10GBase-CX4 is a 10-gigabit Ethernet protocol using 4-laned copper InfiniBand connectors. 10GBase-CX4, developed by IEEE 802.3ak working group, is a lower-cost switch interface. 10GBase-CX4 uses the XAUI (10 Gigabit Attachment Unit Interface) specified in 802.3ae, and the 4X connector used for InfiniBand. Rather than attempt to transmit 10 gigabits over a single copper link, the 802.3ak specification uses four transmitters and four receivers operating differentially over a bundle of very thin twin-axial cables to transmit 2.5G bit/sec each at a baud rate of 3.125 GHz per channel with 8B10B coding. This requires four differential pairs in each direction for a total of eight twin-axial channels per assembly. 10GBase-CX4 can support a cable length up to 25-meter.

10Gbase-E, as defined by IEEE 802.3ae, is for single mode fiber (SMF based on G.652) with 1550 nm laser transceiver with a bandwidth of 10 Gbps. 10GBase-E allows optical signal transmission up to 40km. The 10GBASE-ER media types is designed for use over dark fiber, while the 10GBASE-EW media type is designed to connect to SONET equipment.
