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.
