Following are the major parameters associated with optical light sources:

- - OCh output power
  - OCh wavelength AQ
  - Line spacing
  - Cutoff A (tunable sources)
  - Tunability speed (tunable sources)
  - Spectral width (tunable sources)
  - Line width (light sources)
  - Modulation depth (modulated sources)
  - Bit rate (max-min) (modulated sources)
  - Source noise
