100G 400G Coherent receiver DP-QPSK Coherent receiver Neophotonics Finisar(U2T) CPRV1225A
This coherent receiver integrates a 2X8 90° optical hybrid and 4 balanced detectors with low IQ skew and low noise for free-space coherent communications, satellite optical communications and fiber sensing. Extensive customization is available. The CPRV1225A consists of an integrated polarization beam splitter and four balanced photo-receivers monolithically integrated with optical 90° hybrids.The receiver is a fully differential optical front-end suited for 100 Gbit/s DP-QPSK applications featuring high linearity and high common mode rejection ratio.The optical 90° hybrids demodulate the I/Q incident signal for each respective polarization state using external reference oscillator laser sources.The mixing products are detected by PIN-photodiodes and amplified by trans-impedance amplifiers (TIA) with linear transfer characteristics. All output channels feature integrated peak-detectors for optional AGC-loop operation.The integrated VGA stage offers 20 dB dynamic gain adjustment range and has very low total harmonic distortion.
