BS EN 61290 3 1 is a part of an international multi series standard that discusses test methods for optical amplifiers. BS EN 61290 3 1 applies to commercially available optical amplifiers (OAs) such as optical fiber amplifiers (OFAs), semiconductor optical amplifiers (SOAs) and planar waveguide amplifiers (PWOAs) as classified in IEC 61292 3. BS EN 61290 3 1 describes the methods that
