Hi fayiqa,
Thank you for the suggestion. you made a valid point that for long transmission reach,the effect of dispersion and chirp cannot be really avoided.
I though tried to use fiber bragg grating to compensate both because fiber bragg grating is said to be used for both :
– dispersion compensation using fiber bragg grating ( chirped FBG)
– avoiding frequency chirp (because FBG can be used as filter too)
But to my surprise , the performance didn’t improve a lot.
regards
