Análisis técnico comparativo mediante simulación de los moduladores ópticos externos

Abstract

Nowadays, the optical fiber is positioned as the preferred transmission medium, becoming the global backbone of the internet. To meet the growing demand for high speeds, new technologies have been developed for optical communication systems, including external optical modulation. This type of modulation allows working at high speeds and long distances. The external optical modulators that are widely used in high-performance optical communication systems are the electro-optical modulator and the electro-absorption modulator. The purpose of this technical study is to compare the performance of external electro-absorption and electro-optical modulators, using the OptiSystem simulation software, under different scenarios of single-channel optical systems, in order to determine which modulator is better under certain circumstances. The simulation scenarios were carried out by varying parameters that modify the performance of the communication system, such as the link length and the transmission speed. The analysis is performed by comparing parameters that define the performance of the optical communications system such as transmission speed, link distance, frequency response, time response, OSNR, BER, and eye diagram
