Answer :

Fiber optic cable generally has the fastest transmission rate and highest immunity to electrical noise.

Fiber optic cable transmits data as pulses of light go through tiny tubes of glass. The transmission capacity of optical fiber cable is 26,000 times higher than that of twisted pair cable.They transfer data signals in the form of light and travel hundreds of miles significantly faster than those used in traditional electrical cables. Fiber optic cable is actually composed of two layers of glass: The core, which carries the actual light signal, and the cladding, which is a layer of glass surrounding the core. The cladding has a lower refractive index than the core. This causes Total Internal Reflection within the core. Most fibers operate in duplex pairs: one fiber is used to transmit and the other is used to receive.
