SpectraMux® CWDM

Corning’s coarse wavelength division multiplexers (CWDMs) are integrated optical modules that mux or demux multiple optical signals of different wavelengths in a single fiber. Our CWDM products separate wavelength into bands of 20 nanometers to cover the complete fiber optical communication spectrum from 1270 nm to 1610 nm. These CWDM products cover 4-channel, 8-channel, and 16-channel mux and demux applications, with upgradeability for both four and eight channel types. We also offer optical add-drop modules, or OADMs, with the capability of adding or dropping from one to fifteen channels. Our CWDM products directly address the competitive market needs for metropolitan and access wavelength management. Custom channel plans are available upon request.
