Abstract
An optical network carrying TDMA (time division multiple access) signals includes an optical bus (,) and nodes (RN, TN) which are connected to the optical bus. The optical bus includes at least two co-located optical fiber waveguides (,). At each node a receiver receives an optical data signal transmitted on one of the waveguides and an optical clock signal from another of the waveguides. The node may also include a transmitter, which may take a clock signal from one of the waveguides, modulate it, and output it as a data signal on another of the waveguides.
