  3. JPE Technical review FFE/DFE Equalization + Modulation formats MLSE Pre-Equalization Designs Coding FEC Combinations In access MMF Longer distances In metro Studies Performance Dispersion/OSNR Higher capacity In core Non-Linearities Comparisons

  4. JPE Technical review

  5. JPE Technical review ctd. Topics studied, investigated, demonstrated: • Electronics to mitigate impairments in core: • Channel distortion: Dispersion, SPM, • Timevirying effects: PMD  FFE/DFE: Optimization of taps, transmission efficiency, adaptive schemes  MLSE: Optimization, study on required stages, transmission efficiency  Alternative solution: pre-equalization • Electronics to mitigate impairments in metro/access: • Cost effective, small bandwidth, high capacity systems • Low cost Tx,Rx, MMF  Coherent multi-level systems + equilization  Low cost DML transmission enchancement compensation (FFE/DFE)  MMF transmission equalization with FFE/DFE • Development and study of SQRT equalization
