WDM (Wavelength Division Multiplexing) is to combine a series of optical carrier signals at different wavelengths carrying various information at the transmitter through the Multiplexer and couple them to the same optical fiber for transmission. At the receiver end, the optical signals are separated from each other by a Demultiplexer.(WDM)https://www.glsun.com/product-v28-dwdm-device.html
