hi aabid baba
both problem and solution are well explained in above comments… you just go through them
problem was
OTDV——> optical time domain visualizer
in my system design i require to view the optical signal pulses at various positions in the transmission link OTDV——> optical time domain visualizer..the positions
are….
1}after the MZM 2}after the fiber of 100kms 3} after DCF and amplification.
but there are no. of bits bits missing in the initial stage or time
solution
was suggested by the zulkarnain … and it worked for me… to use user defined bit sequence instead of the random bit sequence gennerator
with regards
