| Direct modulation schemes have attracted increased attention during the past few years because of their intrinsic simplicity and cost-effectiveness, especially when applied to WDM metro and access networks. However, the output power waveform from directly modulated laser is not an exact replica of the modulation current and their instantaneous optical frequency varies with time depending on the changes in optical power (an effect also known as frequency chirp). In this work, using an Optical Communication System Design Software, we studied a directly modulated WDM 10 Gb/s system. We demonstrated that transmission performance depends strongly on DML Extinction Ratio. Furthermore, simulation results provided further details about the effects of DML type (adiabatic or transient chirp dominated) as well as the effects of the ER. These details can provide useful design guidelines for constructing a WDM metro network. | |
