BS EN 61290-3-2:2008 Optical amplifiers. Test methods. Noise figure parameters. Electrical spectrum analyzer method

BS EN 61290-3-2 applies to all commercially available optical amplifiers (OAs), including OAs using optically pumped fibres (OFAs based on either rare-earth doped fibres or on the Raman effect), semiconductor optical amplifiers (SOAs) and planar waveguide optical amplifiers (PWOAs).

The object of BS EN 61290-3-2 is to establish uniform requirements for accurate and reliable measurements, by means of the electrical spectrum analyzer (ESA) method, of the noise figure, as defined in IEC 61291-1.

The test method specified in BS EN 61290-3-2 is based on direct electrical noise measurement and it is directly related to its definition including all relevant noise contributions. Therefore, this method can be used for all types of optical amplifiers, including SOA and Raman amplifiers which can have significant contributions besides amplified spontaneous emission, because it measures the total noise figure.
