This part of IEC 61291 applies to optical amplifier (OA) devices and sub-systems to be used in multichannel applications. For single channel applications, use IEC 61291‑2.

The object of this performance specification template is to provide a frame for the preparation of detail specifications on the performances of OA devices and sub-systems to be used in multichannel applications.

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