METHOD AND APPARATUS FOR DEMODULATING AND REGENERATING PHASE MODULATED OPTICAL SIGNALS |
摘要 |
<p>A DPSK/DQPSK receiver includes an optical splitter that separates the received DPSK/DQPSK optical signal according to an optical power splitting ratio into a plurality of received optical signals. A plurality of optical filters passes a plurality of filtered received optical signals. A plurality of optical detectors generates a plurality of electrical detection signals, each with a power that is related to a power of a respective filtered optical signal. A plurality of amplifiers generates a plurality of amplified electrical signals. At least one electrical signal combiner combines the plurality of amplified electrical detection signals generated by the plurality of optical amplifiers into a combined reception signal.</p> |
