Desarrollo de una cama de pruebas experimental para sistemas IR-UWBoF-IM/DD basándose en el uso de la plataforma de simulación VPIphotonics

Abstract

In this work we describe the design of an Impulse-Radio Ultra-Wide band over Fiber (IR-UWBoF) system implemented on the\linebreak VPItransmissionMaker$^{\textrm{TM}}$ simulation software. This IR-UWBoF system uses the simple and low cost intensity external modulation with direct detection (IM/DD) technique to transmit IR-UWB signals at 1 Gbps of data rate through a standard single mode optical fiber (SSMF) link. We validate our proposal by means of a comparative analysis between the Power Spectral Density (PSD) of IR-UWB signals generated by simulation and the PSDs of signals obtained by an experimental IR-UWBoF IM/DD system. The maximum bandwidth of the proposed system is 10 GHz, which it is determined by the frequency response of the electro-optic modulator and the electric devices used. The analysis of results show that the simulated IR-UWBoF system can be used as an experimental testbed to analyze and to evaluate IR-UWB transmissions through optical fiber links in a fast and accurate manner.
