Optoplex DPSK 光解調器 DLI C+L band DI-C1MLCC006
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.
