Designed for high-density line cards and CFP2 pluggable transceivers, the NeoPhotonics Micro-Coherent Receiver provides advanced demodulation to analyze the state-of-polarization and optical phase of a phase-modulated signal relative to an externally-supplied optical reference. This enables the recovery of the phase-polarization constellation of 100 G/s Dual Polarization Quadrature Phase Shift Keyed (DP-DQPSK) format signals as well as 8-QAM (Quadrature Amplitude Modulation) and 200 Gbps 16-QAM format signals. This ICR is also suitable for 64QAM signals. The ICR incorporates four sets of high-sensitivity balanced photodiodes with four differential linear amplifiers to provide four output channels at 32 GBaud and above. Coherent receiver is compliant with Optical Internetworking Forum standard “Implementation Agreement for Integrated Dual Polarization Micro-Intradyne Coherent Receivers” OIF-DPC-MRX-02.0.
