WDM FILTER BOTTOM Analysis Function
This function enables the collective analysis of multiple items of each channel via the
measured waveforms of multi-channel optical filters.
It also enables filter analysis for multi-mode waveforms, which is different from the
FILTER BOTTOM analysis.
Items for analysis
Item for Analysis Description
Nominal Wavelength Reference wavelength/frequency of each channel.
Bottom Wavelength / Level Peak wavelength/frequency and level of each channel
xdB Notch Width / xdB notch width of each channel and its center wavelength/
Center Wavelength
frequency.
xdB stop-band Wavelength width / frequency width across xdB of each channel.
xdB Elimination band Elimination band that is xdB from the bottom within the test band of
each channel.
6Ripple Max-min level (flatness) within the test band of each channe.
Cross Talk Difference in level between the positions that are xnm away in each
channel.
