Pulse method using a gated optical spectrum analyzer BS EN 61290 10 2 applies to optical fibre amplifiers (OFA) using active fibres, containing rare earth dopants, currently commercially available. The object of BS EN 61290 10 2 is to establish uniform requirements for accurate and reliable measurements of the signal spontaneous noise figure as defined in IEC 61291 1. BS
