• Value of λ sm
λ sm indicates a side move wavelength.
The unit is nm. A value is output down to the third decimal place.
When analysis is impossible, –1 is output.
• Value of L sm
L sm indicates a side mode level.
The unit is dBm. A value is output down to the second decimal place.
When analysis is impossible, –999.99 is output.
• Value of MOFS
MOFS indicates a mode offset (difference in wavelength between the main peak
and side mode).
The unit is nm. A value is output down to the third decimal place.
When analysis is impossible, –999.99 is output.
• Value of STBW
STBW indicates a stop band (interval between wavelengths of both side modes of
main peak).
The unit is always nm. A value is output down to the third decimal place.
When analysis is impossible, –1 is output.
• Value of CNTOFS
CNTOFS indicates a center offset (difference between main peak wavelength and
center wavelength of both side modes).
The unit is always nm. A value is output down to the third decimal place.
When analysis is impossible, –999.99 is output.
