The method (30) comprises configuring an optical source (12, 32, 34, 36) of the communications network to generate an unmodulated optical carrier signal for the said optical channel. The method further comprises determining the optical power (36) of the said unmodulated optical carrier signal (P HIGH )- The method further comprises configuring the said optical source (16) to apply a test modulation pattern (16) to the optical carrier signal, to generate a modulated optical carrier signal. The method further comprises determining the optical power (18) of the said modulated optical carrier signal (P MOD ). The method further comprises determining a power correction factor (20) for the said optical channel by determining the difference between the said optical powers of the said unmodulated optical carrier signal and the said modulated optical carrier signal.

摘要： A connection-oriented communications network (4) comprises a plurality of interconnected nodes (N1-N4, 11-13). A traffic path (N1-N2-N3-N4) can be set up across the network (4). Path delay data is obtained for the traffic path by using control plane signalling messages (e.g. a Resource Reservation Protocol - Traffic Engineering, RSVP-TE signalling message) between nodes of the traffic path. The path delay data can be path delay asymmetry data indicative of an asymmetry in path delay between a forward transmission direction and a reverse transmission direction of the traffic path. Each intermediate node (N2, N3, N4) along the traffic path can form a signalling message for forwarding to the downstream node which includes one or more values of path delay incurred by that node, or an accumulated path delay value. The path delay can result from one or more of mapping delay, Forward Error Correction (FEC) coding and propagation delay.

摘要： A method of demultiplexing client data from a constant bit rate (CBR) optical client serial link into lower bit-rate CBR signals for transmitting over a plurality of wavelength division multiplexed (WDM) optical channels. The method comprises mapping blocks of bytes from a client frame received from the optical client serial link into respective CBR transport frames for transmitting over the respective WDM optical channels and such that the number of bytes in the client frame is the same as the number of bytes in the plurality of respective CBR transport frames. Modifying a number of non-payload bytes from the client frame to carry CBR transport frame control data in each said CBR transport frame.
