    摘要： A synchronous packet switch comprises output modules (12), input modules (16), optical connections (26) and a switch control unit (28). The output modules comprise optical receivers (14) each configured to receive optical signals at a different wavelength. The input modules receive electric signals carrying data cells to be routed. Each input module comprises optical transmitters (18), each configurable to generate an optical signal at a different wavelength, and routing apparatus (20) comprising output ports (22). Each output module has at least one output port allocated to it. The routing apparatus is configurable to route a received optical signal to a selected output port. The optical connections are arranged to couple output ports to respective output modules. The switch control unit controls routing of the optical signals from the transmitters to the output modules and generates a routing control signal (36) for configuring the routing apparatus to route an optical signal from a transmitter to a selected output port.

    摘要： 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.
