Types of Ethernet cable
Ethernet uses one of three standard cable types:
Ethernet
Type
10Base-T
10Base-2
10Base-5
Cable type
UTP
RG-58
RG-11
Impedance
Denomination
100 Ohm
50 Ohm
50 Ohm
unshielded twisted pair
Ethernet thin
Ethernet thick (yellow
cable)
Note: Although 8-conductor telephone wire is commonly used for 10Base-T connections, this type
wire is not the correct 100 ohm UTP, as it does not use twisted-pairs. Using such wire may cause
excessive crosstalk, resulting in a large number of collisions and poor network performance.
