Notes:
ꢀ. The output power is coupled into a ꢀ m single-mode fiber. Minimum output optical level is at end of life.
2. The relationship between FWHM and RMS values for spectral width can be derived from the assumption of a Gaussian shaped spectrum which
results in RMS = FWHM/2.35.
3. These are unfiltered ꢀ±-9±% values.
