Análisis de las técnicas de Multiplexación por división de longitud de onda (WDM) y su simulación mediante el software OptiSystem.

Abstract

The purpose of this title work is to analyze the techniques of WDM (Wavelength Division Multiplexing), and its subsequent simulation. In the first instance, the theoretical study of each of the techniques will be carried out, such as: CWDM (Coarse Wavelength Division Multiplexing), DWDM (Dense Wavelength Division Multiplexing) and UDWDM (Ultra ‐ Dense Wavelength Division Multiplexing)showing its advantages and disadvantages with which a comparative table of the aforementioned techniques is made. After that, the simulation in Optisystem of different scenarios is proposed, varying the separation between channels that differentiates these techniques, which allows observing their behavior. The results are obtained for each of the multiplexing techniques and depending on the required application it will be used in practice. It is observed in the results stage that UDWDM is the technique that stands out the most due to the lower separation of channels which allows for greater wavelengths and therefore greater channel bandwidth.
