The present work aimed to investigate by means of numerical simulations, a device able to perform 3R regeneration (Re-amplifying, Re-timing and Re-shaping) fully propagated signal in an optical communication system for optical fiber with bit rate of 10 Gbit/s, the initial transmit power 0 dBm and wavelength of 1550 nm. As an ally to the regeneration process using dispersive and nonlinear effects of self-phase modulation (SPM), cross-phase modulation (XPM) and four-wave mixing (FWM) in a Mach-Zehnder Interferometer, whose one of the arms is composed of a Highly Nonlinear Photonic Crystal Fiber (HNL-PCF).
The simulations were performed using OptiSystem commercial software of company canadian Optiwave Corporation. System performance was analyzed by comparing the values of the quality factor (Q-factor), of the bit error rate (BER), of optical spectrum and the optical signal-to-noise ratio (OSNR) optical signals are regenerated, before regenerated and degraded in the entrance and exit of the proposed system. Through this project, it was possible to obtain an efficient signal regeneration, with optimal values of OSNR, quality factor (Q-factor) and low bit error rate (BER).
