Phase modulation provides a beneficial alternative to the traditional amplitude modulation found in optical communication systems. Differential-Phase-Shift-Keyed (DPSK) modulation, when compared to On-Off-Keyed (OOK) modulation, can provide a 3-dB gain in sensitivity (when using balanced detection) as well as increased resilience against non-linear effects. The trend of growing bandwidth consumption in fiber-optic networks led first to the emergence of Wavelength-Division-Multiplexed (WDM) systems, and now to the consideration of advanced modulation formats such as DPSK and other phase-intensive formats .
