摘要： An optical multi carrier signal has a modulation format and has many individual carrier signals. Parameters of the signal are controlled by receiving (100) an indication of individual carrier transmission performance of the individual carrier signals, and selecting (110) parameter values for the individual carrier signals, the parameter values comprising both a carrier FEC overhead and a carrier bandwidth for the modulation format. Selection is made according to the indicated individual carrier transmission performance and according to an overall spectral efficiency of the multi carrier signal. The selected parameter values are output (120, 124, 125, 126, 127) for control of the optical multi carrier signal. By selecting values for both parameters rather than either one, better optimisation can be obtained since they are interdependent. The control can have better granularity than changing modulation format, and can make better use of bandwidth or improve the overall capacity.

摘要： A method for optimisation of the number and location of regenerative or non-regenerative repeaters in a WDM link made up of N spans connected in a succession of N-1 intermediate sites to form link sections separated by sites containing regenerative repeaters, comprises a step for defining the number of regenerative repeaters needed and giving them a first location. Said step comprises the phases of defining targets OSNRs (VOSNRT) as a function of the number of spans and the type of fibre used in the spans, and defining a possible section between an initial site and a final site, appraising a metric function VM for said possible section obtained as a function of the difference between the OSNR (VOSNR) at the final end of the first span of said possible section and the corresponding target OSNR (VOSNRT) given by the number of spans in said possible section. If the appraised metric function VM satisfies an established quality parameter, add to the possible section the following span in the link and again appraise the metric function for said new possible section obtained as a function of the difference between the OSNR (VOSNR) at the final end of the first span of the possible section and the corresponding target OSNR (VOSNRT) with the new number of spans in the possible section. Said steps are repeated iteratively while adding spans to the possible section until the metric function VM no longer satisfies the quality parameter and one returns at the end site preceding the last span added and positions a regenerator in said site. The procedure is repeated until the end of the new section is identified or to exhaustion of the spans of the link.

摘要： A radio base station (10) has a baseband controller (20) coupled to a radio head (30) by an optical wavelength division multiplexed link to pass downlink signals on a first wavelength (100), and uplink signals on another wavelength (110). A compensating delay is applied to one of the signals to compensate for a difference in transmission times between the downlink and the uplink signals. The compensating delay can be controlled according to the difference in wavelengths. By compensating for such differences in transmission times, synchronisation problems can be avoided or ameliorated, or transmission distances can be increased. This can result in more flexibility in choice of wavelengths, fiber types and fiber lengths, and greater resilience. This can enable simpler installation or configuration, or reconfiguration without needing to take care to restrict the selection of wavelengths on the WDM link or restrict the length of the link for example.
