Coaxial Cable
Coaxial cable consists of a conductor surrounded first by an insulating material,
then by a braided conductive sheath, as shown in Figure 7-3. In LAN applications,
the sheath is electrically grounded and serves as a shield that protects the inner
conductor from electrical noise. The shield also helps eliminate signal loss by
keeping the transmitted signal confined to cable.
Coaxial cable can carry a wider range of frequencies and can be used in greater
lengths than twisted pair cable. However, coaxial cable is more expensive than
twisted pair.
