Abstract:
An optical network comprising:(a) an optical bus including at least two co-located optical fibre waveguides;(b) a plurality of transmitter nodes, each transmitter node including a transmitter stage connected to the optical bus and arranged to receive an optical write clock signal from one of the fibre waveguides and to write an optical data signal, in a time slot synchronized to the optical write clock signal, onto another one of the fibre waveguides, each transmitter stage including a modulator and being arranged to write the optical data signal by modulating the write clock signal received from said one of the waveguides; and(c) at least one receiver node, the receiver node including a receiver stage for receiving an optical data signal output onto the optical bus by the transmitter stage of a transmitter node, the receiver stage also being arranged to read an optical read clock signal from a second one of the optical fibre waveguides.
