摘要： A method and apparatus for switching an optical data stream via an optical network node, capable of switching optical data received at input ports to output ports. The method includes the following steps performed by a processing chain upon detection of a stream at a given wavelength by a given input port: determining a resource of the node based on a predetermined routing policy such that, for a given wavelength common to source and destination nodes of the stream, routing within the network is carried out according to a routing tree covering the network, a root of the tree being the destination node; consulting an occupancy table for the resource, indicating if at least one possible preceding stream is using the resource; determining a delay to be applied by the processing chain to prevent a collision between the stream and the possible preceding stream; and configuring the processing chain to apply the delay.

摘要： The differential group delay is measured in an optical fiber connection for an optical signal undergoing a phase modulation BPSK or DPSK by a digital signal at a given rate. A polarization controller at an emerging end of the connection scans polarization states of the modulated optical signal. An emulator iteratively introduces an additional delay in the modulated optical signal emerging from the connection and combines the delayed modulated optical signal and the non delayed modulated optical signal which are both polarized along two orthogonal axes into a resulting optical signal. A polarization controller and a fixed polarizer select a polarization state in the resulting optical signal along one of bisecting lines of the orthogonal axes into a linearly polarized signal. An eye diagram or a spectrum of the polarized signal is acquired by a digital oscilloscope or an optical spectrum analyzer to determine the differential group delay.
