woven to block any outside interference. This metal
mesh is again shielded by an outer covering of a thick
material (usually PVC) known as jacket.
Although coaxial cabling is difficult to install, it is
highly resistant to signal interference. It can support
greater cable lengths between network devices and
can offer greater bandwidth than twisted-pair cable. However, attenuation in coaxial cables is much
higher as compared to twisted-pair cables due to which the signal weakens rapidly. As a result, repeaters
are to be used frequently to boost up the signals. Coaxial cables are capable ...
