Abstract

A TRAVES DE UN AMPLIFICADOR MULTIFASE DE FIBRA OPTICA, EN EL QUE SE EXPANDEN POR DIFERENTES CAMINOS Y SE SUPERPONEN EN EL MISMO SENTIDO FRACCIONES DE SEÑALES OPTICAS, SE PRODUCE EN EL RECEPTOR OPTICO DE RUIDOS ADICIONALES JUNTO A LOS RUIDOS CAUSADOS A TRAVES DE LA EMISION ESPONTANEA EN EL AMPLIFICADOR DE FIBRA OPTICA. SE PROPONE UN AMPLIFICADOR BIFASICO DE FIBRA OPTICA, EN EL QUE UNA PRIMERA PIEZA CONDUCTORA DE FIBRA OPTICA (F1) SE BOMBEA FRENTE O EN LA DIRECCION DE EXPANSION DE LA SEÑAL OPTICA Y LA SEGUNDA PIEZA CONDUCTORA DE FIBRA OPTICA (F2) SE BOMBEA EN O EN DIRECCION CONTRARIA A LA DIRECCION DE EXPANSION DE LA SEÑAL OPTICA. HAY DISPUESTOS UNA FUENTE DE LUZ BOMBEADA (1), LAS PIEZAS CONDUCTORAS DE LUZ (F1, F2) Y UN ACOPLADOR (K1,K2,K3), DE TAL MODO QUE LAS SEÑALES QUE SE EXPANDEN POR DIFERENTES CAMINOS NO SE SUPERPONGAN EN LA MISMA DIRECCION.
