Abstract:
A method provides and/or controls an optical signal, wherein a control signal and at least one data signal are optically processed into a combined signal of substantially constant optical power. The level of the at least one data signal is substantially maintained within the combined signal. In addition, an according device is provided. Suitable for compensation of Raman tilt in WDM communication systems.
