Abstract
A method (10) of configuring a synchronous optical switch to route received data cells. The synchronous optical switch comprises optical switch transmitter modules, each comprising tunable optical transmitters, optical switch receiver modules, each comprising optical receivers, and optical connections between the transmitter modules and receiver modules. For each optical switch transmitter module, the method: assigns (12) wavelengths associated with the received data cells to the transmitters such that each wavelength is assigned to a different transmitter; and generates (14) a control signal for controlling the operating wavelength of each transmitter. For each wavelength, the method: allocates (16) to each transmitter an optical connection such that each optical switch transmitter module has no more than one connection exiting it at said wavelength and each optical receiver module has no more than one connection entering it at said wavelength; and generates (18) a control signal for connecting each transmitter to the respective optical connection.
