摘要： Path computation through nodes of a communications network to meet a desired security level against unauthorised physical access to the path, involves receiving a request (200) for selection of a new path, and using a record (210) of connectivity of the nodes and links with indications of a security level against unauthorised physical access to the path. This can enable the path routing to be made so as to assure a given level of security of the underlying hardware of nodes and links, in networks where not all parts can provide such security. Nodes can report their current security levels to update the record. A previously selected path can be validated by comparing indicated current security levels of the nodes of the path with the desired security level.

摘要： A method (10) of compensating for channel power depletion induced by Raman amplification noise in a hybrid distributed Raman amplifier-Erbium doped fibre amplifier. In the method, an equivalent noise figure is determined (12) for a virtual amplifier equivalent to the hybrid distributed Raman amplifier-Erbium doped fibre amplifier, and having an input power equal to the input power of the Erbium doped fibre amplifier when the distributed Raman amplifier is off and an output power equal to the Erbium doped fibre amplifier output power. A compensation power, dependent at least in part upon the equivalent noise figure, is determined (14). A control signal is provided (16) for controlling the hybrid amplifier such that an optical signal amplified by the hybrid amplifier has a total output power equal to a predetermined nominal output power plus the compensation power.

摘要： Apparatus (10) for an optical communications network has optical paths for optical traffic, and optical ports (20, 40), one of which is an unused output port (20). A security monitoring system (30) has a blocking part (50) coupled removably to the unused output port to occupy it to prevent unauthorised access. An optical detector (60) can detect optical signals passing through the unused output port to the blocking part, and there is alarm circuitry (70) 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： A path computation client (PCC) (21) can request a path computation element (PCE) (22) to compute a path across a wavelength switched optical network. PCC (21) sends a request which identifies end nodes (10). The end nodes (10) can support a plurality of possible values of a transmission parameter, such as modulation format or Forward Error Correction (FEC) type.

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.
