How does optical fiber differ from CAT cables?
Fiber optic cable uses glass or plastic strands to transmit data using light pulses, as opposed to twisted pair cable, which is copper and uses electrical pulses. Fiber optic cable can carry signals further, with less loss, and due to the lack of copper, it is not susceptible to electrical interference. Unfortunately all of these advantages come at a cost; fiber optic cable is more costly to install and terminate than twisted pair cable.
