In general, fiber optic cable provides the highest electrical noise immunity and the fastest transmission rate.
As light pulses pass through small glass tubes, fiber optic cable transfers data. Twisted pair cable's transmission capacity is 26,000 times lower than optical fiber cable's transmission capacity. Compared to conventional electrical lines, they can transmit data signals in the form of light over distances of hundreds of kilometers. The core, which carries the real light signal, and the cladding, which is a layer of glass around the core, make up the two layers of glass that make up fiber optic cable. Compared to the core, the cladding has a lower refractive index. Total Internal Reflection occurs within the core as a result. most fibers
