Explanation
Setting WDM Filter Analysis Parameters
The WDM FIL-PK analysis function parameters may be broadly divided into the two
types shown below.
Parameter settings may be changed as desired according to the details of the particular
analysis.
• Parameters related to channel detection
• Parameter settings for each analysis item
The following is an explanation of each of the parameters.
See appendix 6, “Optical Filter Analysis Function” for a description of the parameters.
Parameter Settings Related to Channel Detection
These parameters are used to set algorithms and threshold level for WDM channel
detection.
ALGO
Depending on the selected algorithm, select one of the following four algorithms for WDM
channel detection and reference wavelength analysis on each channel.
• PEAK
• MEAN
• GRID FIT
• GRID
The channel detection and reference wavelength analysis results for each channel vary
depending on the algorithm selected.
• When PEAK is selected
Each mode peak is detected as a channel.
The peak wavelength of each channel is the reference wavelength.
