In the 70’s Xerox DEC and Intel standardize the Ethernet system. Call “DIX” standard a 10 mbps system ( 10 million 1s and 0s ) using coax cable 10base5 10 for the speed “Base” stand for Baseband and 5 for the distance ( 500m ).The Institute of Electrical and Electronic Engineers (IEEE) released the Ethernet standard in 1983 called the IEEE 802.3 and in 1985, version 2 (IEEE 802.3a) was released.
10Base-T
The number 10 represent the frequency in Mhz and translate it to 10 Mbit = 1.2 Mbytes per secondes .The T stand for Twisted Pair .
10Base-2
Use a black Coax Cable named “Twin wire cable” “Thin Ethernet” or RJ58 cable wich could go up the 100 Mhz ( 100 Mbit ) with a maximum of 185m and they were using BNC connectors.
10Base-5
Use a yellow Coax Cable named “Thickwire cable” with a maximum of 500m with special connectors to interface the network card .
10Base-F
Use optic cable for 10Mbit networks
10Base-35
Use broadband coaxial cable. It is able to support multiple baseband channels for a maximum of 3600m
100Base-TX
The TX (sometimes refered as “T” only) means it’s a CAT5 UTP straight through cable using 2 of the 4 available pairs and supports speeds up to 100Mbits. Maximum length is 100m.
100Base-T4
The T4 means it’s a CAT5 UTP straight through cable using all 4 available pairs and supports speeds up to 100Mbits. Maximum length is 100m.
100Base-FX
The FX means it’s a 2 strand fiber cable and supports speeds up to 100Mbits. Maximum length is usually upto 2000m.
