ABSTRACT:
An optical switch comprises a hub and a plurality of nodes with the hub being connected to each node by an optical communication link dedicated for clock signals and by an optical communication link dedicated or data signals. In use the hub transmits a clock signal to all of the nodes; each node re-transmits a copy of the clock signal to the hub and transmits a data signal to the hub. The hub returns each re-transmitted clock signal to its respective node and forwards a copy of each data signal to all of the nodes so that each node can receive a selected data signal by processing the re-transmitted clock signal.
