Análisis de convergencia de transmisión de video y datos en una red de acceso PON

Abstract

This paper presents an analysis on the convergence of video and data transmission in a PON (Passive Optical Network) access network. The research focused on optimizing parameters such as RF power, bias voltage by using advanced tools such as Lab- VIEW NXG software and hardware equipment such as the USRP 2944-R. Critical variables including transmission power, Mach-Zehnder modulator bias voltage and block error rate (BLER) were evaluated using mathematical models and experimental tests to determine optimal configurations. The study showed that a transmission power of -5.89 dBm and a bias voltage of 3.2 V allowed a stable and high-quality transmission. The elimination of the optical amplifier located after the receiver was essential to avoid signal saturation, significantly improving the transmission quality and reducing errors in the constellation diagram. In addition, it was identified that the sensitivity of the system without an amplifier reached -35 dBm for a BLER of 10−3. The results obtained lay a solid foundation for future developments in optical access networks.
