Abstract :
We present a novel hardware architecture for digitally adaptive feed-forward equalization (FFE) on a Virtex-II FPGA and show its performance in a time-varying IM/DD optical link. Our solution can be scaled to various bit rates and our digital adaptation unit is able to track time-varying channels well within 1ms.
