Abstract

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 degradation and filtering effects are studied through the monitoring of the eye opening penalty (EOP). It is observed that the shape of the input signal, which depends on the laser parameters, has a major influence on the EOP. Fiber based pre- and post-compensation schemes are 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.
