Resumen
CAMAS-ANZUETO, J.L.; CERECEDO-NUNEZ, H.H.; KUZIN, E.A. y MENDOZA-VAZQUEZ, S.. Caracterización de una señal pulsada propagándose en fibra óptica. Rev. mex. fis. [online]. 2003, vol.49, n.2, pp.144-149. ISSN 0035-001X.
In this paper we describe the basic principles of an optical fiber communication system and we show experimental propagation of a pulsed signal. We invest the broadening and attenuation of this pulses under adverse conditions of temperature, belts and twist. We also describe details of the mechanism of generation, propagation and reception of this pulses. For pulse generation it was used a COMBO circuit and two clocks (4.096 MHz and 8 KHz.). For transmission of this pulses it was used a 10 m multimodal optical fiber. Results of experimental analysis shows that pulse codification by this set up is safety and easy to build.
