Optical DPSK Demodulator Polarization Beam Combiner passive optical network and fiberOptical DPSK demodulator is a Delay Line Interferometer (DLI), converts phase modulation to amplitude modulation over the entire C+L band in support of data transmission rates of 2. 5, 10 or 40 Gb s. The DPSK demodulator is based on a patented free space optical design, which is compact, athermal and polarization independent.
