A passive optical network employing wavelength dependent routing uses two-phase signalling between a network controller and terminals. In a first phase, terminals are informed of the wavelength channel allocated to them for a second signalling phase, groups of terminals being allocated to each channel. In the second signalling phase, control signals indicate to the terminal the wavelength and time slots allocated to the terminal in the following data transmission phase.
