,nThank you! I have solved this question in this transmission by your method.n But when I change a parameter to get a new transmission, I meet a new problem.n
There is a warning that Insufficient number of peaks detected to calculate free spectral range.
nThe FSR is 0:n
nquality factor is a point :n
nI decrease the pit excursion from 7 to 3n
The problem still exists.nCan you tell me how to solve this problem?n
