IEC 61291

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 Ed. 4.0 b:2018

Optical amplifiers - Part 1: Generic specification

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)

Optical amplifiers - Part 2: Single channel applications - Performance specification template

IEC 61291-2:2016(E) provides a performance specification template which applies to optical amplifiers (OAs) to be used in single channel applications. Multichannel applications are covered in IEC 61291-4. The object of this performance specification template is to provide a frame for the preparation of performance standards and/or product specifications on the performance of OA devices to be used in single channel applications. In the performance standards or product specifications, other specifications such as ratings, operating conditions, tests and pass/fail criteria could be included in addition to the requirements based on this performance specification template. Product specification writers may add specification parameters and/or groups of specification parameters for particular applications. However, product specification writers should not remove specification parameters specified in this standard. 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: - the title of this standard has been changed from digital applications to single channel applications; - the scope has been changed and, as a result, the titles of tables have been changed; - Terms and definitions have been revised; - three tables regarding the minimum list of relevant parameters of power amplifiers, pre-amplifiers and line amplifiers based on semiconductor optical amplifier (SOA) components have been added; - transient parameters have been added in the minimum list of relevant parameters of pre-amplifiers and line amplifiers based on optical fibre amplifier (OFA) module. Keywords: optical amplifiers (OAs) used in single channel applications

Optical amplifiers - Part 4: Multichannel applications - Performance specification template

"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 ."

Optical amplifiers - Part 5-2: Qualification specifications - Reliability qualification for optical fibre amplifiers

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). Keywords: optical amplifiers (OAs), optical fibre amplifiers (OFAs)

Optical amplifiers - Part 6-1: Interfaces - Command set

"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."
