Abstract
La red incluye segmentos de fibra óptica (3) y equipamiento convencional (1, 2, 4), mientras que un sistema de distribución cuántica de claves (QKD) dispone de dispositivos de intercambio de información mediante canal cuántico (7, 8). El sistema comprende al menos un filtro (6) para cada uno de los referidos dispositivos de intercambio (7, 8) y al menos un bloque de gestión de canales clásicos y cuánticos (5) que reduce el ruido en canales cuánticos y que presenta al menos funciones de: atenuación de la potencia de inserción de los canales clásicos en la red; polarizaciones distintas en los diversos canales clásicos y cuánticos; y cambios de asignaciones de longitudes de onda tanto en canales clásicos como cuánticos.
