• Nowadays, communication system by 10 gigabit capable symmetric passive optical network (XGS-PON), provide the highest bandwidth and speed of all modern communication networks, however, these networks present difficulties on responding to degradations in transmission in optical fiber communication systems. Effects such as dispersion, attenuation and nonlinear effects lead to the degradation and/or lossing of information in the link. In the case of optical fiber, chromatic dispersion (CD) is the degradation that most affects communication systems, this effect happens because of the pulses emitted by the source are made up of different wavelengths, which in turn travel at different speeds, which generates different arrival times to the receiver, causing a temporary widening of the pulse and giving rise to the emergence of intersymbolic interference [1]. The CD impact is highly significant in the quality of the transmitted optical signal, since it restricts the transmission speed and link length. Therefore, it is necessary to implement compensation techniques that contribute to reduce the degradations caused by chromatic dispersion This article presents the elaboration of a chromatic dispersion compensating module implemented and co-simulated in Matlab of MathWorks and OptSim of Rsoft, in order to mitigate the degrading effects that the CD brings, and in this way to find solutions in the field of digital processing of signals that support the demands of modern architectures.
