Optical amplifiers. Test methods - Noise figure parameters. Electrical spectrum analyzer methodWhat is BS EN 61290 3 2 Electrical spectrum analyzer method about? BS EN 61290 3 2 is an international method that discusses the test methods for optical amplifiers. BS EN 61290 3 2 applies to all commercially available optical amplifiers (OAs), which include 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).
