Abstract :
This letter considers optical dispersion compensation in the electrical domain. It is shown that after electrical detection the spectrum of the optical signal suffers a frequency cutoff. The maximum frequency, which can be detected by the square-law detector, is inversely proportional to dispersion in the optical line. This puts a limit on the maximum value of optical dispersion, which can be compensated by electrical equalizers
