Fiber optic demodulator 21.9GHz DQPSK Demodulator Optoplex DI-C0KLCC002
Optoplex’s Optical DQPSK demodulator converts differential quadratural phase modulation to amplitude modulation over the entire C+L band in support of data transmission rates of 20 or 40 Gb/s. DQPSK demodulator is designed for the next generation optical communications systems utilized in commercial, defense and space exploration markets. The device plays a key role in improving signal quality and performance to meet the expanding demand for higher data rates and more complex transmission formats within current and next generation systems without major capital expenditure. DQPSK demodulator uses half the transmission rate to achieve the same data rate (20-Gb/s system for 40-Gb/s data rate, with four phase states as compared to two in DPSK format). A lower transmission rate saves cost on many other components and electronics and is more tolerant to dispersion. 20-Gb/s system is the highest transmission rate possible for the 50-GHz channel spacing system. Optoplex’s fully integrated DQPSK demodulator combines a power splitter and both I- and Q-arms.
