Optical amplifiers - Maximum permissible optical power for the damage-free and safe use of optical amplifiers, including Raman amplifiers1 Scope and object This part of IEC 61292, which is a technical report, applies to all commercially available optical amplifiers (OAs), including optical fibre amplifiers (OFAs) using active fibres, as well as Raman amplifiers. Semiconductor optical amplifiers (SOAs) using semiconductor gain media are also included. This technical report provides a simple informative guideline on the threshold of high optical power that causes high temperature damage
