BS EN 61290 1 is a safety standard on optical amplifiers. BS EN 61290 1 applies to all commercially available optical amplifiers (OAs) and optically amplified subsystems. BS EN 61290 1 applies to OAs using optically pumped fibres (OFAs based on either rare earth doped fibres or on the Raman effect), semiconductors (SOAs), and waveguides (POWAs). The object of BS EN 61290 1 is to establish uniform
