Procedure
• Perform a bottom search within the range of parameter Test_Band/2 while centering
on reference wavelength (λi) of each channel and obtain the bottom level (LBi).
• Perform a peak search within the range of parameter Test_Band/2 while centering on
the point (λi−λSP) that is obtained by subtracting the parameter SPACING from the
reference wavelength λi of each channel. Then, obtain the peak level (LPLi).
• Perform a peak search within the range of parameter Test_Band/2 while centering on
the point (λi+λSP) that is obtained by adding the parameter SPACING to the reference
wavelength λi of each channel. Then, obtain the peak level (LPRi).
• Use the values obtained in the above procedure to obtain the left and right cross talks
(XTLi, XTRi) of each channel from the following equations:
XTLi = Lbi − LPLi
XTRi = Lbi − LPRi
