The IEC 61290, 61291, and 61292 series focuses on optical amplifiers, including those based on semiconductors (SOAs). IEC 61290 is a 22 part series covering methodology of analysis using optical amplifiers. IEC 61291 contains general and performance specifications. Lastly, IEC 61292 is a series of technical reports (IEC/TR) that provides additional information.
IEC 61291-1:2018 applies to all commercially available optical amplifiers (OAs) and optically amplified assemblies. It applies to OAs using optically pumped fibres (OFAs based either on rare-earth doped fibres or on the Raman effect), semiconductors (SOAs), and waveguides (POWAs). The object of this document is - to establish uniform requirements for transmission, operation, reliability and environmental properties of OAs, and - to provide assistance to the purchaser in the selection of consistently high-quality OA products for his particular applications. Parameters specified for OAs are those characterizing the transmission, operation, reliability and environmental properties of the OA seen as a "black box" from a general point of view. In the sectional and detail specifications a subset of these parameters will be specified according to the type and application of the particular OA device or assembly. This fourth edition cancels and replaces the third edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - terms have been added for parameters from IEC 61290-4-3 and IEC 61290-10-5; - Clause 4 Classification has been removed, since this system is judged to be unused; - the definition of polarization mode dispersion (PMD) has been simplified. Keywords: optical amplifiers (OAs)
IEC 61291-2:2023 is available as IEC 61291-2:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61292-2:2023 provides a performance specification template applicable to optical amplifiers (OAs) used in single channel applications. Multichannel applications are covered in IEC 61291-4. The objective of this template is to provide a framework for the preparation of performance standards and/or product specifications defining the performance of OA devices used in single channel applications. In addition to the requirements specified in this template, a performance standard or product specification could include other parameters, such as ratings, operating conditions, tests, and pass/fail criteria. For a particular application, product specification writers could add specification parameters and/or groups of specification parameters to this template, without removing the parameters specified in this document. This fifth edition cancels and replaces the fourth edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the test methods for gain ripple in Table 2, Table 4 and Table 6 refer now to the IEC 61290 1 series; - the SOA definition (3.1.3) refers now to IEC 61931.
"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 ."
IEC 61291-5-2:2017(E) applies to optical amplifiers (OAs) and optically amplified, elementary sub-systems for terrestrial applications, using active fibres (optical fibre amplifiers (OFAs)) containing rare-earth dopants, which are commercially available. The black box approach is used in this document. The black box approach is adopted in order to give product specifications which are independent of OA implementation details. For reliability qualification purposes, some information about the internal components is needed; these internal parts are themselves treated as black boxes. This document gives requirements for the evaluation of OA reliability by combining the reliability of such internal black boxes. The object of this document is to specify the minimum list of reliability qualification tests, requirements on failure criteria during testing and on reliability predictions, and give the relevant normative references to establish a standard method for the assessment of the reliability of OFA devices and sub-systems in order to minimize risks and to promote product development and reliability qualification. This second edition cancels and replaces the first edition published in 2002. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) removal of the contents on the relating quality management system from scope, terms and definitions, and the reliability requirements; b) moving fit-rate calculation to Annex B (informative); c) change of requirements for shock test; d) amendment of abbreviations related to changes a) and b).

"IEC 61291-6-1:2008 describes the optical amplifier command set (OACS) for use in communicating with and controlling intelligent optical amplifiers. These amplifiers can receive and possibly respond to such commands by using resident firmware or may be optical amplifiers controlled by a microprocessor. This standard addresses the structure and content of the command set to control optical amplifiers. It does not cover the physical or hardware interface, which is assumed to exist for communication of this command set to the optical amplifier."
