4×2MIMO polarization processing
Analog-domain equalization
The high-bandwidth analog FFE completes key equalization before digital processing and supports polarization and chromatic-dispersion compensation.
Analog MIMO + IM/DD DSP
Analog MIMO performs front-end equalization before the IM/DD DSP, recovering high-speed signals with a lower digital compute load.
Power and cost
To address the high power of digital equalization, the analog approach reduces digital processing pressure and provides a lower-power, lower-cost domestic technology path.
