Description
Overview
GAOTek add drop multiplexer is a low cost WDM transmission technology for man access layer. In principle, CWDM use optical multipliers to reuse optical signals of different wavelengths to a single fiber for transmission. At the receiving end of the link, the optical demultiplexes is used to decompose the mixed signals in the fiber into signals of different wavelengths and connect them to the corresponding receiving equipment
