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. Also provides a simple informative guideline on the threshold of high optical power that causes high-temperature damage of fibre. Optical safety for manufactures and users of optical amplifiers by reiterating substantial parts of existing standards and agreements on eye and skin safety are also discussed.
