Optoplex Corporation, a leading supplier of innovative photonic fiber-optic components, modules and subsystems for dynamic wavelength management and signal conditioning, today announces its volume production and shipment of DPSK family of products. In the past 12 months, more than 40 customers, including major tier one companies, have chosen Optoplex’s products due to their superior performance and quality. This places Optoplex as a leading supplier for DPSK applications.

Differential Phase-Shift Keying (DPSK) demodulator, also called "Delay Line Interferometer (DLI)", converts phase modulation into amplitude modulation over the entire C+L band in support of data transmission rate of 10 or 43 Gb/s. It is designed for next generation optical communications systems utilized in commercial, defense and space exploration markets. The device improves 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 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. Further, its DPSK exhibits a total polarization-dependent phase shift less than 2 degrees over the entire operation temperature range with an extinction ratio of greater than 25 dB. The DPSK demodulator will cover all channels in the C+L band and may be configured for wide tuning range (a few FSR), semi-tunable (±3 GHz) or purely passive operation modes. A super-fast tunable version (<1 ms) is also under development.
