    • An optical signal transmission apparatus for transmitting a plurality of data signals comprising a plurality of inputs for receiving a respective one of the data signals and delivering the respective data signal with a controlled phase and at a controlled data rate. A plurality of optical carrier signals having different wavelength is generated. Each of a plurality of first modulators is operative for modulating a respective one of the optical carriers with a respective data signal to provide a first-modulated optical carrier signal. An optical signal-routing device has a plurality of input ports, each port being for receiving a respective one of the first-modulated optical carrier signals and delivering it to the output port of the device. The apparatus further comprises further modulators for further modulating each of the first-modulated optical carrier signals in dependence upon a clock to provide a plurality of further-modulated optical carrier signals; and a feedback arrangement, including the optical signal-routing device, for feeding back a proportion of each of the further modulated optical carrier signals to a respective input for controlling the phase and rates at which the input delivers the data signal to the first modulator in dependence upon the further modulation to thereby synchronize each input data signal to the clock. The optical signal-routing device delivers each of the further-modulated signals applied to its output to a respective input along a path which is dependent upon the wavelength of the signal.

    • An apparatus and method of transmitting a plurality of polarized signals having different wavelengths through a length of signal transmission cable which changes the polarization of the signals in correspondence with their amplitudes and wavelengths. A dynamic filter capable of differential adjustment of the amplitudes of the signals and a polarizing element are provided in series with the length of signal transmission cable and the amplitudes of the different wavelength signals are so adjusted that the polarization states of the signals move towards alignment with the low-loss axis of the polarizing element. An advantage provided by the apparatus and method is that the high-amplitude signals are aligned with the low-loss axis of the polarizing element while low-amplitude noise is aligned with the high-loss axis of the polarizing element, resulting in an improvement in signal-to-noise ratio.

    • Flows are grouped according to a first flow rate and a second flow rate. Each flow comprises of a plurality of packets. The flows in the first flow rate are sorted according to an arrival time of a first packet in each flow. These flows are placed in a first FIFO (first-in-first-out) queue with a flow having an earliest first packet arrival time located at a head of the first FIFO queue. The flows in the second flow rate are sorted according to an arrival time of a first packet in each flow. These flows are placed in a second FIFO queue with a flow having an earliest first packet arrival time located at a head of the second FIFO queue. A comparison is performed to select a packet from between the first packet of the flow at the head of the first FIFO queue with the first packet of the flow at the head of the second FIFO queue.
