In an optical signalling system, simultaneous signals are circulated on a looped path and fed out sequentially to a tuneable receiver. Conversely, sequential signals may be buffered in the loop and fed out simultaneously to a number of receivers. The system is suitable for use in a passive optical network employing wavelength-dependent routing, terminals transmit request packets (requesting a data transmission slot) in a common signalling time slot. Different delays are then applied to packets on different wavelength channels, allowing a number of request packets to be processed in sequence by a single optical receiver at the network controller.
