40Gb / s differential phase shift keying Optoplex receivers (DPSK Rx) is based on advanced optical DPSK demodulation mode, the application for next-generation 40Gb / s transmission systems. It incoming DPSK demodulated optical signal into an amplitude modulated signal by a radio frequency (RF) output. This receiver supports up to 43Gb / s transfer rate in a small volume of packages.

Phase modulation can provide better than conventional amplitude modulation dispersion properties, it is because the strength of the phase-modulated optical signal remains unchanged, thus avoiding the nonlinear effects due to changes in signal strength caused by the amplitude modulation, and thus to extend the signal transmission distance.

  

Integrated DPSK receiver via equilibrium binding DPSK demodulator and receiver to achieve a smaller volume. Compared with discrete components, integrated optical receiver demodulator output signal from the detector directly into balance, resulting in between small insertion loss and branching optical path difference, and eliminate the coiled length of optical fiber and optical fiber matching degree.

Integrated receiver demodulators are micro-optical free space-based technology patents Optoplex. Through which convert the incoming phase-modulated optical signal into an amplitude modulated signal, is then received by a balanced detector. Due to the use of unique materials and design, integrated receivers on insertion loss and phase exhibits a high degree of non thermal behavior. RF output issued by the balance detector and then through a limiting transimpedance amplifier (TIA) to increase the gain. In addition, Optoplex also monitor the input signal and the signal attenuation up to 3dB of capabilities in one device.

40Gb / s integrated differential phase shift keying Optoplex receiver may offer different free spectral range, such as 43GHz, 50GHz, 57GHz, or other customer-specified values.
