Optical DPSK Demodulator

Optoplex’s Optical DPSK Demodulator, also known as 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 designed for phase modulated optical communication

systems utilized in commercial, defense and space exploration markets. The DPSK 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. 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, semitunable

or purely passive. Dual-Rate DPSK Demodulator is also available.
