Frequency-Domain Equalization for Coherent Optical Transmission Systems
Coherent communications Fiber optics links subsystems
2015/5/26
Frequency-domain equalization (FDE) has been attracting much attention for high-speed long-haul transmission over fiber-optic channels. Two FDE configurations for coherent optical transmission are pre...
Self-Coherent Optical Transmission Using a Narrow Linewidth Tunable Slotted Fabry-Perot Laser
Coherent communication Semiconductor lasers
2015/6/4
A narrow linewidth slotted Fabry-Perot laser has been employed in a self-coherent optical transmission system. A comparison of the system performance of the tunable slotted laser with a SG-DBR laser h...
Dispersion Compensation Using Decision-Feedback MLSE for Spectrally-Efficient Optical Transmission
Dispersion Compensation MLSE Spectrally-Efficient Optical Transmission
2015/7/17
We propose a novel decision-feedback maximum likelihood sequence estimation, and numerically demonstrate its use in 10GS/s 8-ASK-DQPSK (8-ASK-QPSK) systems to significantly improve the dispersion tole...
