CWDM Optical Add-Drop Multiplexer
Pictures and Schematic Diagram
The main function of the optical add-drop multiplexer is to add a low-bandwidth signal to or extract a low-bandwidth signal from an existing high-bandwidth data stream. The optical multiplexer facilitates the dynamic reconfiguration of optical networks in that the wavelengths carried over the optical fiber are properly distributed.
