FIBER BASED DISPERSION COMPENSATION SCHEMES IN NONLINEAR FIBERS FOR LASER-DIODE PULSES IN HIGH BIT-RATE IM DD SYSTEMS/

The combined effects of chromatic dispersion and self-phase modulation are numerically investigated for a 10 Gbit/s IM/DD system over 100 km of standard single-mode fiber for input signals modeled by stochastic rate equations for single-mode semiconductor lasers. Signal degradati on and filtering effects are studied through the monitoring of the eye opening penalty (EOP). It is observed that the shape of the input sig nal, which depends on the laser parameters, has a major influence on t he EOP. Fiber based pre- and post-compensation schemes an compared for different values of the laser parameters and compensation length. In most cases, pre-compensation yields lower eye-opening penalty for the laser pulses analysed. (C) 1997 Elsevier Science B.V.
