Abstract :
A lightwave component analyser is used to measure the frequency response of a 6300km optically amplified testbed. The position of the nulls is shown to be very sensitive to the fibre parameters and the optical power level and agrees well with numerical predictions. Such measurements could be used to detect any changes occurring between factory tests and the installation of a long-haul optically amplified system.
