Interferometría a través de procesamiento digital de señales para determinar la eficiencia en la ventana 1550nm.

Fiber to the Home (FTTH) networks have revolutionized Internet access by providing higher speed and greater stability in data transmission. However, optical signal propagation in the 1550 nm window presents technical challenges related to attenuation and dispersion, affecting measurement accuracy. This research aims to analyze advanced interferometric techniques based on digital signal processing (DSP) to enhance anomaly detection in FTTH networks. Descriptive and exploratory methodologies were applied to evaluate various interferometric techniques and DSP algorithms, including the Fourier transform, cross-correlation, and curve fitting. Simulations demonstrated that combining these techniques reduces measurement errors, improves accuracy, and ensures greater stability in data transmission. The results show that Mach-Zehnder interferometry, Fourier interferometry, and Fabry-Perot interferometry are highly effective for signal characterization in the 1550 nm window. Additionally, the use of advanced algorithms mitigates noise impact and optimizes data interpretation in optical networks. In conclusion, the application of interferometric techniques combined with DSP represents a viable solution to improve monitoring and maintenance in FTTH networks. Further experimental studies in real environments and the broader integration of these technologies in the telecommunications industry are recommended.
