摘要: A received RZ-DPSK signal is guided to an interferometer. The interferometer comprises a 1-bit delaying element in upper arm. balanced photodiode converts pair of optical signals output from the into electrical signal. high-pass filter, which has cut-off frequency equal or approximately symbol rate transmission data, filters photodiode. BPSK demodulator circuit demodulates filter.
