Abstract: Systems and methods are provided for achieving graceful bandwidth scaling (i.e. higher data transmission rates) for Coarse Wavelength Division Multiplexing (CWDM) and CWDM-4 technologies. Examples utilize a waveband architecture built around the CWDM wavelengths. This waveband architecture adds additional wavelength transmission channels (which may equate to faster data transmission rates) while maintaining backwards compatibility with existing CWDM/CWDM-4 technologies. Examples may include waveband devices (e.g. waveband light sources, waveband transmitters, waveband receivers, waveband transceivers, etc.) designed to operate with one or more CWDM wavebands while maintaining backwards compatibility with existing CWDM-4 technologies.
