| 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 (DML) is not an exact replica of the modulation current and their instantaneous optical frequency varies with time depending on the changes in optical power (frequency chirp) and the values of intrinsic parameter of laser. In this work, by means of an Optical Communication System Design Software, we researched a directly modulated WDM 2.5 Gb/s optical ring network. We demonstrated that the transmission performance depends strongly on DML characteristics, fiber dispersion and impulse response of optical filter. Furthermore, simulation results provide more details about the effects of DML type (adiabatic or transient chirp dominated) as well as the effects of the optical filter bandwidth. These details can provide useful design guidelines for building a WDM metro network. | |
