Center wavelength/frequency: spectral center-of-mass for the peak.
Peak power (dBm): peak signal power.
Bandwidth 3.00 dB: bandwidth measured by taking the width of a
signal at 50 % linear power of the peak or -3 dB from the peak.
Bandwidth 20.00 dB: bandwidth measured by taking the width of a
signal at 1 % linear power of the peak or -20 dB from the peak.
Left SMSR: Left side-mode suppression ratio. It is the power difference
between the main mode and the most powerful outstanding
side-mode on the left.
Right SMSR: Right side-mode suppression ratio. It is the power
difference between the main mode and the most powerful outstanding
