Product Description
A CWDM (Coarse Wavelength Division Multiplexer) is a passive wavelength division multiplexing device used in optical fiber communication networks. It can combine multiple optical signals of different wavelengths into a single optical fiber for transmission, or separate signals of different wavelengths at the receiving end.
