Abstract :
Electronic equalizers are more and more applied in optical transmission systems to compensate for static as well as time varying fiber distortions. In this paper we investigate the performance of 4-states and 16-states MLSE equalizers in 10 Gbit/s field trials over buried single mode fibers. Our results show that the MLSE equalizer enables the joint compensation of chromatic dispersion up to 4480 ps/nm and polarization mode dispersion up to 92 ps. This will increase the uncompensated transmission length and enables a more robust and flexible optical link design.
