EVS-EN 61290-10-1:2009

This part of IEC 61290 applies to optical amplifiers (OAs) using active fibres and waveguides,containing rare-earth dopants, currently commercially available.The object of this standard is to establish uniform requirements for accurate and reliablemeasurements of the signal-spontaneous noise figure as defined in IEC 61291-1.The test method independently detects amplified signal power and amplified spontaneousemission (ASE) power by launching optical pulses into the OA under test and synchronouslydetecting "on" and "off" levels of the output pulses by using an optical sampling switch and anoptical spectrum analyzer (OSA).
