Abstract
We demonstrate a novel receiver concept for duobinary signals that allows for data recovery with a sensitivity of −39.5dBm (88 Photons/bit, BER=1.10−9, 231-1 PRBS). Oversampling together with maximum likelihood sampling phase estimation results in superior back-to-back performance without lowering the large chromatic dispersion tolerance of duobinary signaling.
