IEC 61291-4:2011 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. This third edition cancels and replaces the second edition published in 2008 and constitutes a technical revision. The main significant changes are the transient parameter test methods, IEC 61290-4 series, have been added to Tables 1, 2, and 3.

This publication is to be read in conjunction with IEC 61291-1:2006.
