Fiber optic is interesting because it takes a very old concept that is the manipulation of light, it is nothing more than that, the controlled manipulation of light. Cable internet companies if we go back to history, the Egyptians themselves controlled the light by means of mirrors to illuminate inside the incredible pyramids ... Precursors of the optical fiber?
Today the manipulation of the light is controlled within a cable, with special terminations and special plates that make the transmission possible and that I will detail throughout this humble note.
