In this paper, signal statistics and their utilization for detection in narrowly filtered equalized high-speed fiber-optic communications are investigated experimentally. Tradeoffs between log-likelihood metric applications and oversampling are covered in detail. It is, for the first time, demonstrated that performance loss in bandwidth-limited systems can be nearly fully recovered (to within 0.5 dB) by taking advantage of band-width-limitation-induced noise correlations and oversampling.

Nyckelord: Colored noise, fiber-optic communications, maximum-likelihood sequence, detection, Viterbi algorithm, likelihood sequence estimation, polarization-mode dispersion, bit-error-rate, lightwave systems, analytical expressions, chromatic, dispersion, optical amplifiers, transmission, receiver, performance
