Please refer to Neophotonics 200G ICR https://www.neophotonics.com/product/hbw-icr/ Overview Designed for next-generation high baud rate linecards, the NeoPhotonics High Bandwidth 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 200 G/s Dual Polarization Quadrature Phase Shift Keyed (DP-DQPSK) format signals as well as 8-QAM (Quadrature Amplitude Modulation) and 400G 16-QAM format signals. .
