This performance specification template applies to single channel optical amplifier (OA) devices to be used in digital applications. For multichannel applications, use IEC 61291 part 4. The object of this performance specification template is to provide a frame for the preparation of detail specifications on the performances of single channel OA devices to be used in digital applications. Detail 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.
