10GBase-SW, as defined by IEEE 802.3ae, is mode of 10GBase-S for multimode fiber (MMF) with a 850-nm laser transceiver with a bandwidth of 10 Gbps. It can support up to a 300 meters cable length. The 10GBASE-SW media type is designed to connect to SONET equipment. 
Standard Organization: IEEE
Reference Document: IEEE 802.3ae

10GBASE-T is a standard proposed by the IEEE 802.3an committee to provide 10 Gigabit/second connections over conventional unshielded twisted pair cables (Category 5e or Category 6 or Category 7 cables). 10GBASE-T allows the conventional RJ-45 used for Ethernet LANs. 10GBASE-T can support signal transmision at the full 100m distance specified for LAN wiring.

Reference Document: IEEE 802.3an

10GBASE-ZR, supporting link lengths of up to about 80 kilometers on SMF, is a 10 Gigabit Ethernet specification that is not part of the IEEE 10 Gb Ethernet standard but is built according to Cisco optical specifications. 10GBase-ZR uses the 1550nm laser wavelength.

10Broad36 is an obsolete standard for carrying 10 Mbit/s Ethernet signals over a standard 75-ohm CATV cable with a 3600 meter range.
Standard Organization: IEEE
Reference Document: IEEE 802.3

10-Gigabit Ethernet offers data speeds up to 10 billion bits per second over an Ethernet network. Built on the Ethernet technology, it offers similar benefits to those of the preceding Ethernet standard. 10-Gigabit Ethernet is used to interconnect local area networks (LANs), wide area networks (WANs), and metropolitan area networks (MANs). 10-Gigabit Ethernet uses the familiar IEEE 802.3 Ethernet media access control (MAC) protocol and its frame format and size. However, it supports full-duplex, but not half-duplex, mode and only functions over optical fiber. Therefore, it does not need the carrier-sensing multiple-access with Collision Detection (CSMA/CD) protocol used in other Ethernet standards.

Reference Document: IEEE 802.3ae+D687

1Base5 refers to an obsolete standard to carry 1 Mbps over unshielded twisted pair for StarLAN Ethernet.
Standard Organization: IEEE

2 Binary 1 Quaternary (2B1Q) is a full duplex physical layer encoding method used in ISDN and other digital communication technologies. In 2B1Q, two binary bits are encoded into one quaternary signal, doubling the effectiveness of transmission.
Standard Organization: ANSI
Reference Document: T1.601
