Electronic Dispersion Precompensation With a 10-Gb/s Directly Modulated Laser

We present 10-Gb/s transmission with a directly modulated laser (DML) avoiding inline dispersion compensating by electronic precompensation. To apply this technique of electronic dispersion precompensation to DMLs, a new approach based on artificial neural networks will be introduced. We realized a transmission of 190-km standard single-mode fiber in a laboratory experiment. Simulations show that compensation of up to 350 km can be achieved.
