OSNR-aware control of optical white boxes on elastic optical networks

Asia Communications and Photonics Conferene (ACP) © OSA 2016 Results of optical white boxes on Elastic Optical Networks with adaptive modulation format and symbol rate simulations demonstrate that synthesized nodes improve capacity under low loads while preserving performance of existing ROADMs for higher loads

Network Savings Enabled By Probabilistic Shaping And Nonlinear Compensation

Probabilistic shaping and intrachannel nonlinear compensation are advanced techniques with good potential to increase the reach of future optical transmission systems. While nonlinear compensation has attracted considerable attention from the research community, especially the digital backpropagation algorithm, probabilistic shaping for optical communications remains only partially explored. Both techniques are not mutually exclusive, but the research and development efforts allocated to one or the other technique will depend on their potential. This paper discusses advantages and disadvantages of both techniques, and network scenarios where one, the other, or both techniques should be applied.18th International Conference on Transparent Optical Networks (ICTON)JUL 10-14, 2016Univ Trento, Fac Letters & Philosophy, Trento, ITAL

Network Cost Savings Enabled By Probabilistic Shaping In Dp-16qam 200-gb/s Systems

We evaluate potential network cost savings enabled by probabilistic shaping in DP-16QAM 200-Gb/s systems, based on experimental measurements and analytical derivations. The results indicate savings of up to 6.7% in the average number of transceivers.Optical Fiber Communications Conference and Exhibition (OFC)MAR 20-24, 2016Anaheim, C
