Fundamental Limits on the Performance of Maximum-Likelihood Sequence Estimation in Dispersive Optical Links

摘要

MLSE experiments supporting 10Gbit/s, 1000km uncompensated G.652 fiber transmission, have been successfully performed. However, a residual 2dB OSNR-penalty, non-linear effects and Viterbi processor complexity may constitute fundamental limitations to actual MLSE exploitation in long-haul links.
