Abstract

EL DISPOSITIVO COMPRENDE, CONECTADAS A LAS SALIDAS DE MATRICES DE CONMUTACION ELEMENTALES (M SUB 1... M SUB J... M SUB M), DISPOSITIVOS DE CONVERSION ELECTROOPTICOS (1) ACOPLADOS A FIBRAS OPTICAS. LAS SALIDAS DE LOS DISPOSITIVOS DE CONVERSION ELECTROOPTICOS, CONECTADOS A LAS SALIDAS DEL MISMO RANGO (Y SUB K), DIFERENTES MATRICES ELEMENTALES ESTAN ACOPLADOS EN PARALELO A TRAVES DE LAS FIBRAS OPTICAS (F SUB 1K...F SUB MK), A UNA MISMA FIBRA OPTICA DE SALIDA (F SUB K), ELLA MISMA CONECTADA A UNA SALIDA CORRESPONDIENTE (S SUB K) A TRAVES DE UN DISPOSITIVO DE CONVERSION OPTO-ELECTRICA (2). UNA SOLA DE LAS SALIDAS (Y SUB K) DEL MISMO RANGO K DE LAS DIFERENTES MATRICES ELEMENTALES PUEDE ESTAR ACTIVA EN UN MOMENTO DADO. LA INVENCION SE APLICA, EN PARTICULAR, A LOS DISPOSITIVOS DE CONMUTACION ACOPLADOS A FUENTES DE SEÑAL DE VIDEO, POR EJEMPLO PARA LA VIGILANCIA DE REDES FERREA, EN LAS QUE SE DESEA EVITAR LA DIAFONIA ENTRE LAS SEÑALES A EMITIR Y EVITAR LAS PERTURBACIONES DE ORIGEN ELECTROMAGNETICO.
