摘要：An optical signal, which is a low-speed signal superimposed on a high-speedphase modulated optical signal by intensity modulation, is used. In an optical receiver
apparatus , a received signal is split, and one of the split signals is O/E converted and lowfrequency component alone is extracted via a filter . A clock is extracted from low-frequency component by CDR, and is compared with a preset frequency. Using thefrequency difference obtained, dispersion compensation is performed with low accuracy.Next, the amount of phase control of the delay interferometer is adjusted so that theamplitude of the electrical signal is maximized. An error rate is measured, and fineadjustment is performed to improve the error rate.
