hi all,
post compensation include that
microwave filtersfilter… used only for the coherent modulation schemes.hence not used so much
FFE—-feed forward equalizer
DFE—-distributed feedback equalizer..
MLSE—maximum likelihood equlizer.(best of all post compensation methods)
it must be noted here that main compensation seheme is the inline compensation… pre and post compensation are just to ehance the inline compensation…
hope this clears all the confusions regarding the dispersion compensation.
