This part of IEC 61291 provides a performance specification template which applies to optical amplifiers (OAs) to be used in single channel applications. Multichannel applications are covered in IEC 61291‑4.

The object of this performance specification template is to provide a frame for the preparation of performance standards and/or product specifications on the performance of OA devices to be used in single channel applications. In the performance standards or product specifications, other specifications such as ratings, operating conditions, tests and pass/fail criteria could be included in addition to the requirements based on this performance specification template.

Product specification writers may add specification parameters and/or groups of specification parameters for particular applications. However, product specification writers should not remove specification parameters specified in this standard.
