With the optical fiber application develop, the CWDM and DWDM was designed in the optical network . The early fiber optic transmission systems put information onto strands of glass through simple pulses of light. A light was flashed on and off to represent the “ones” and “zeros” of digital information. The actual light could be of almost any wavelength (also known as color or frequency) from rough...
