https://www.neophotonics.com/product/type-1-icr/ Overview NeoPhotonics Type 1 Integrated 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 200G 16-QAM format signals. The ICR incorporates four sets of high-sensitivity .
