We demonstrate dispersion monitoring of differential phase-shift keying (DPSK) modulated optical transmission system by measuring RF components of detected optical signal. The results show that this scheme can realize dispersion monitoring up to 4320ps/nm and sensitivity up to 15.5(ps/nm)/dBm. The effect of OSNR on the performance of the monitoring system are studied and discussed.
