The DPSK demodulator is designed for phase modulated optical communication systemsutilized in commercial, defense and space exploration markets. The device plays a key role in improvingsignal quality and performance to meet the expanding demand for higher data rates and more complextransmission formats within current and next generation systems without major capital expenditure.Optoplex’s DPSK Demodulator is based on a patented free-space optical design, which is compact, athermal and polarization-independent. The measured frequency drift over temperature is only ~0.02 GHz/°C for our standard passive device. Further, this DPSK Demodulator exhibits a total polarization-dependent phase shift of less than 2 degrees over the entire operating temperature range with a high extinction ratio. Optoplex’s DPSK Demodulators can be configured to be fully tunable, colorless tunable or purely passive. Dual-Rate DPSK Demodulator is also available.

DQPSK Demodulator
Differential Quaternary Phase-Shift Keying (DQPSK) is the four-level version of DPSK. DQPSK transmits two bits for every symbol (bit combinations being 00, 01, 11 and 10) and has an additional advantage over conventional binary DPSK. DQPSK has a narrower optical spectrum, which tolerates more dispersion (both chromatic and polarization-mode), allows for stronger optical filtering, and enables closer channel spacing. As a result, DQPSK is the only modulation format which allows processing of 40Gb/s data-rate in a 50-GHz channel spacing system.
