Coaxial Cable

Networking Topics > Layer 1 Physical > Coaxial Cable

Coaxial network cable is available in two types. Thicknet and thinnet, as the names suggest they derive from the diameters of the cables. Due to the nature of coaxial cable, it is particularly good at keeping interference at bay, hence it can be run for longer distances than either UTP or STP before repeaters are required to regenerate and retime the signal.

Pros

Can be used in long cable runs without using repeaters
Good resistance to EMI and RFI
Less expensive than Fibre optic cable

Cons

Thicknet is very rigid and hard to install
Installation requires extra special care when terminating the connections to avoid connections that reflect signals back down the cable.
More expensive to install that STP or UTP
