Multi-chip joint maximum likelihood sequence estimation (MLSE) is proposed and shown to outperform joint MLSE, achieving 330 km optically-uncompensated 10 GS/s DQPSK signal transmission and less than 3 dB OSNR penalty for 100 ps DGD.
We demonstrate a chromatic dispersion monitoring method for NRZ-DPSK signals using asynchronous delay-tap sampling technique and Hausdorff distance measure. The result shows this method can be used for residual dispersion monitoring with high nonlinear tolerance.
We propose a novel decision-feedback maximum likelihood sequence estimation, and numerically demonstrate its use in 10 GS/s 8-ASK-DQPSK (8-ASK-QPSK) systems to significantly improve the dispersion tolerance, without increasing the computation complexity exponentially with the format-level number.
We demonstrate DPSK signal dispersion monitoring by measuring low frequency RF power. This scheme can realize dispersion monitoring up to 4320 ps/nm with sensitivity to 0.045 dBm/ps/nm. OSNR effect on the monitoring system is studied and discussed.
