1. A light source having a first mode and a second mode, the light source comprising:
at least a first laser array, wherein:
in the first mode, the first laser array emits optical signals of only a first wavelength within a first Coarse Wavelength Division Multiplexing (CWDM) passband, wherein the first CWDM passband is a spectrum of wavelengths that includes a first CWDM wavelength; and
in the second mode, the first laser array emits optical signals of at least the first wavelength within the first CWDM passband and a second wavelength within the first CWDM passband.
