Ethernet Standards
Historically, CSMA/CD bus networks are also referred to as Ethernet and are generally implemented as a 10 Mbps baseband coaxial cable network or twisted pair cable (“Category 5”).
The standard documents (ISO 8802.3) support other cable media and transmission rates as follows:
10BASE-2 - Thinwire coaxial cable (0.25 inch diameter). 10 Mbps, single cable bus.
10BASE-5 - Thickwire coaxial cable (0.5 inch diameter). 10 Mbps, single cable bus.
10BASE-T - Unscreened twisted pair cable (0.4 to 0.6mm conductor diameter). 10Mbps, twin cable bus.
10BASE-F - Optical fiber cables, 10 Mbps, twin fiber bus.
1BASE-5 - Unscreened twisted pair cables. 1 Mbps, twin cable bus.
10BROAD-36 - Cable Television (CATV) type cables, 10 Mbps, Broadband.
