Wavelength Division Multiplexer (WDM) is the device which uses multiple optical maser to transmit multi beam of different wavelengths of laser technology through a single fiber. Each signal is transmitted in its unique channel after the data (text, voice, video and so on) modulated. WDM can increase the existing fiber infrastructure for phone companies and other operators.
DWDM (dense wavelength division multiplexing) system can support more than 150 different wavelengths of light beam transmitted simultaneously, and each beam peaked at 10Gb/s data rates. This system provides data transmission over 1Tb/s rate but the cable is smaller than a human hair.
Wavelength division multiplexing technology as a system concept, there are 3 modes, wavelength division multiplexing at 1310 nm and 1550 nm wavelength, CWDM (Coarse Wavelength Division Multiplexing) and DWDM (Dense Wavelength Division Multiplexing).
