A device and method for correcting for timing jitter of an optical data puls e in an optical transmission system. During transmission data pulse may suffer jitter. Its arrival time at a node may be temporally offset from its predict ed arrival time. Data pulses are timed so that they may be received at a detect or disposed downstream of said node at a predetermined time. The device includi ng a source of chirped optical pulses and a node, which has a first input arranged to receive a chirped optical pulse, the node having a second input arranged to receive a data pulse. The node including an optical gate arrange d to generate an output pulse in response to said first pulse and said data pulse received at said first and second inputs, respectively, having a wavelength dependent upon the time t at which said data pulse is received at said second input. The device further including an optically dispersive medi um after passage through which, the output pulses are correctly retimed.</SDOAB >
