The light pulses aren't just fading; they are spreading out. Like runners in a marathon who start together but finish miles apart, the different "modes" of light are arriving at different times. The sharp "1s" and "0s" of the digital world are blurring into a grey smear. Like runners in a marathon who start together
Optical communication systems have revolutionized the way we transmit and receive information. These systems use light to carry information through optical fibers, offering high-speed data transfer rates, low signal attenuation, and immunity to electromagnetic interference. One of the most comprehensive resources on optical communication systems is the book "Optical Communication Systems" by John Gowar.
