Detailed explanation-1: -Fiber optic cables are able to transmit data faster than copper cables because they use light instead of electrical pulses to carry data from one point to another. This light is able to travel a lot further and a lot faster than copper cables in a much shorter amount of time.
Detailed explanation-2: -Fiber optic internet is currently the fastest, most-reliable internet service available. Fiber increases download and upload speeds and offers users faster access to various media types and larger file sizes.
Detailed explanation-3: -Engineers have set a new speed record for data transmission through a standard diameter optical fiber. By beaming 55 “modes” of signals down a single-core optical fiber, the team was able to transmit at a data rate of 1.53 petabits per second (Pbit/s).
