Abstract

Système de communication optique temporel asynchrone ayant:
un central (SN), des circuits d'émission de terminal (UE), des circuits de réception de terminal (UR), et des serveurs de diffusion (BS), reliés par des liaisons optiques (UEL ; URL ; BL) au central. Le central est constitué par un dispositif optique de commutation spectro-temporel (SSTSN), un moyen de commande (CPU) et un générateur de signaux de synchronisation (CKU). Le dispositif de commutation (SSTSN) est relié optiquement aux circuits d'émission de terminal, aux circuits de réception de terminal, aux serveurs de diffusion et à des circuits d'émission de configuration (CE), d'émission de signalisation (SE), de réception de configuration (CR), et de réception de signalisation (SR) du moyen de commande.
Le générateur de signaux de synchronisation est relié par une première liaison (H1) au dispositif de commutation et par une deuxième liaison (H2) au moyen de commande (CPU) lui même relié par une liaison de commande (CB) au dispositif de commutation (SSTSN).
Le système utilise conjointement un premier ensemble de fréquences optiques de transmission (Fa) et un deuxième ensemble de fréquences optiques de commande (Fb) pour la commutation. Asynchronous time optical communication system having:
a central office (SN), terminal transmission circuits (UE), terminal receiving circuits (UR), and servers diffusion (BS), linked by optical links (UEL; URL; BL) at the central. The exchange consists of an optical device for spectro-temporal switching (SSTSN), a control means (CPU) and a synchronization signal generator (CKU). The device switching (SSTSN) is optically connected to the transmission circuits terminal, terminal receiving circuits, servers broadcast and configuration transmit circuits (CE), signaling transmission (SE), configuration reception (CR), and signaling reception (SR) of the control means.
The synchronization signal generator is connected by a first connection (H1) to the switching device and by a second connection (H2) to the control means (CPU) itself connected by a control link (CB) to the switching device (SSTSN).
The system jointly uses a first set of optical transmission frequencies (Fa) and a second set of optical control frequencies (Fb) for switching.
