Document Type and Number:
Japanese Patent JP2818481
Kind Code:
B2
Abstract:
Asynchronous optical time-division multiplexing communication system having: a central station (SN), terminal transmission circuits (UE), terminal reception circuits (UR), and broadcasting servers (BS), linked by optical links (UEL; URL; BL) to the central station. The central station consists of a spectrum-time switching optical device (SSTSN), a control means (CPU) and a synchronisation signal generator (CKU). The switching device (SSTSN) is linked optically to the terminal transmission circuits, to the terminal reception circuits, to the broadcasting servers and to circuits for configuration transmission (CE), for signalling transmission (SE), for configuration reception (CR), and for signalling reception (SR) of the control means. The synchronisation signal generator is linked by a first link (H1) to the switching device and by a second link (H2) to the control means (CPU) itself linked by a control link (CB) to the switching device (SSTSN).
The system uses in conjunction a first set of optical transmission frequencies (Fa) and a second set of optical control frequencies (Fb) for the switching.
