PDM-DPSK demultiplex

In addition to the usual PDM-DQPSK demultiplex with its EPC1000 endless polarization controller Novoptel has now also tested PDM-DPSK demultiplex with interference detection. The principle is explained on pp. 5-6 of the EPC1000 application note 01. Polarization tracking was tested down to BER = 10-9. PDM-DPSK is known to be more robust than PDM-DQPSK.
