CPRV1010A
Product Description
The coherent receiver module CPRV consists of four balanced photo-receivers and two integrated optical 90° hybrids and 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 coherent receiver contains two optical multi-mode interferometers where the incident signal is I/Q-demodulated for each respective polarization state using external reference oscillator laser sources. The mixing product is guided into waveguide-integrated pin-photodiodes and an electrical transimpedance amplifier (TIA) with linear transfer characteristic.
All output channels feature integrated peak-detectors for optional AGC-loop operation. The receiver offers shut-down capability which disables all rf-outputs. The integrated VGA stage offers 20 dB dynamic gain adjustment range and has very low total harmonic distortion.
