Abstract:
We propose a hardware- and DSP-efficient simplified coherent PON insensitive to frequency offset and phase noise leveraging unipolar PAM-M modulation. We demonstrate a 40-ns preamble for burst mode detection. Power budgets of 31.8dB and 42.8dB are achieved after 25-km transmission at 200-Gb/s and 100-Gb/s, respectively.
