Ethernet Cable

The basics


(IEEE) Institute Electrical & Electronic Engineers

IEEE is used to define network standards

10 Base2 (IEEE 802.3a)
10 Base5 (802.3)
100 Base-T 802.3i
1000 Base-TX 802.3x


To break the above up so it is more understandable the numbers on the left hand side represent the number of megabits per second and transmitted.

e.g., 10. 100, 1000 megabits per second

The word base indicates that baseband signalling is used.

The numbers 2 & 5 refer to the coaxial cable segment length

The letters represent the type of cable being used

F = Fibre optic

T = Copper unshielded twisted pair

Ethernet uses baseband signalling

802 IEEE Standards

Ethernet operates at layer 2 of the OSI model, the lower half of the data link layer which is known as the MAC sub-layer and the physical layer
