DP-QPSK Demodulator, Optoplex HB-C0GLCC018, 2×8 Coherent Mixer To be used for optical coherent detection such as DP-QPSK receivers, Optoplex’s ten-port 2×8 Coherent Mixer (aka QPSK mixer) combines the incoming signal with a local oscillator to generate eight light states in the complex-field space. The eight light output signals can then […]
