Bro,
I cannot access it because it does not open from optisystems version 14! That is why I requested you to kindly change the FBG wavelength and make it same as the one I gave above.
For each user – 2 FBGs for encoder, 4 FBGS (2 top, 2 bottom for complementary subtraction) at decoder.
This is the file. I think you helped Miss Kaur with it already.
And if you cannot change it, can you please let me know if the attached file works/runs or not?
