“…The communication traffic volume handled by trunk optical transport networks has been increasing year by year [1]. The resultant change in traffic patterns not only requires a quantitative increase in total traffic volume, but also requires an increase in the speed of individual clients.…”

Abstract:We report for the first time, the impact of cross phase modulation in WDM optical transport networks employing dynamic 28 Gbaud PMmQAM transponders (m = 4, 16, 64, 256). We demonstrate that if the order of QAM is adjusted to maximize the capacity of a given route, there may be a significant degradation in the transmission performance of existing traffic for a given dynamic network architecture. We further report that such degradations are correlated to the accumulated peak-to-average power ratio of the added traffic along a given path, and that managing this ratio through pre-distortion reduces the impact of adjusting the constellation size of neighboring channels.

“…INTRODUCTION dynamic and configurable optical layer and control plane [1] is a direct consequence of increasing traffic demand [2] and the associated power consumption of electronic switching. This is particularly true for shorter links across the network, where the improved optical signal-to-noise ratio (OSNR) would allow the use of a high capacity channel.…”

“…According to the forecasted impending "capacity crunch", we are on the verge of approaching the fundamental limit of existing standard single-mode fiber (SSMF), which is mainly attributed to fiber non-linearity [1][2][3]. Hence, the ongoing rapid development of spacedivision multiplexing (SDM) transmission systems is expected to provide a viable strategy to increasing capacity of optical links.…”

Abstract:We experimentally verify the advantage of employing advanced coding schemes such as space-time coding and 4 dimensional modulation formats to enhance the transmission performance of a 3-mode transmission system. The performance gain of space-time block codes for extending the optical signal-to-noise ratio tolerance in multiple-input multiple-output optical coherent spatial division multiplexing transmission systems with respect to single-mode transmission performance are evaluated. By exploiting the spatial diversity that few-mode-fibers offer, with respect to single mode fiber back-to-back performance, significant OSNR gains of 3.2, 4.1, 4.9, and 6.8 dB at the hard-decision forward error correcting limit are demonstrated for DP-QPSK 8, 16 and 32 QAM, respectively. Furthermore, by employing 4D constellations, 6 × 28Gbaud 128 set partitioned quadrature amplitude modulation is shown to outperform conventional 8 QAM transmission performance, whilst carrying an additional 0.5 bit/symbol.
