摘要： A method of monitoring a differential group delay, DGD, of an optical communications signal having a polarisation multiplexed modulation format is described. The method includes the steps of receiving a signal and performing analogue to digital conversion of the signal to generate a digitised signal corresponding to one polarisation of the signal and to generate another digitised signal corresponding to another polarisation of the signal, and applying a polarisation mode dispersion, PMD, compensation to each of the digitised signals. The method further includes the steps of obtaining an indication of the channel transfer function of the optical communications signal, determining a DGD in dependence on the indication of the channel transfer function, determining a delay between the PMD compensated digitised signals, subtracting the delay from the DGD to obtain a corrected DGD, and generating and transmitting a monitoring signal with an indication of the corrected DGD.

摘要： Apparatus for an optical communications network has optical paths for optical traffic, and optical ports, one of which is an unused output port. A security monitoring system has a blocking part coupled removably to the unused output port to occupy it to prevent unauthorized access. An optical detector can detect optical signals passing through the unused output port to the blocking part, and there is alarm circuitry configured to output an alarm signal based on the detecting of the optical signals. This monitoring can help make the node more secure from interference or from eavesdropping. By blocking the port, the monitoring can be independent of the type of signals on the optical paths. The system can be passive or active, and does not require a change in the installed node configuration and so can be added easily to existing infrastructure.

摘要： An optical transmitter has a modulator for modulating data onto an optical signal for transmission to the receiver, the modulated signal having components at one or more constellations of points of different amplitudes and phases. The modulator is tunable such that distortions of the points of the one or more constellation can be tuned, and a tuning controller is provided for receiving a feedback signal from the receiver indicating a distortion measured at the receiver, and for tuning automatically the modulator to adjust the modulation based on the received feedback signal to pre-compensate for the measured distortion. Such pre-compensation can reduce the amount of distortion in the transmission system and thus enable more transmission capacity, without the need for a complex transmitter.

摘要： A wavelength division multiplex optical ring network comprises optical fibre (1-4) arranged in a ring configuration and a plurality of doped fibre optical amplifiers (17-20) arranged in the ring. The spectral response in the ring is configured such in use amplified spontaneous emission (ASE) noise circulates around the ring in a lasing mode to clamp the gain of each doped fibre optical amplifier. Each optical amplifier (17-20) includes respective control means (28) which in use control the optical amplifier to produce a substantially constant output power or to maintain a substantially constant pump power. In the event of loss of the lasing peak, detection means switches the doped fibre optical amplifiers to a different mode of gain control, for example, a mode to produce constant gain at the value before the loss of the lasing peak. Optionally, after a predetermined delay, the optical amplifiers may revert to constant output power or pump power mode. Loss of the peak could be detected by a peak detection circuit (27), which filters by means of filter (26) a fraction of the input or output power of the optical amplifier using splitters and/or by detection of a drop in amplifier input power.
