IEC 61291-2:2023

Overview - IEC 61291-2:2023 (Optical amplifiers - Single channel performance template)

IEC 61291-2:2023 is the fifth edition of the IEC performance specification template for optical amplifiers (OAs) used in single channel applications. It provides a standardized framework for preparing performance standards and product specifications that define the functional and testable performance of single‑channel optical amplifiers. This edition updates the 2016 version and introduces technical changes such as revised references for gain‑ripple test methods and an updated SOA definition reference.

Key topics and technical requirements

• Performance specification templates
  • Templates cover power amplifiers, pre‑amplifiers and line amplifiers for single channel use.
  • Minimum parameter lists are provided separately for optical fibre amplifiers (OFA) components/modules and semiconductor optical amplifiers (SOA) components (see Tables 1–6).
• Test references and methods
  • Test methods for power, gain and noise are referenced to the IEC 61290 test‑method series (e.g., IEC 61290‑1, IEC 61290‑3).
  • Gain ripple test methods now refer explicitly to the IEC 61290‑1 series.
• Definitions and terms
  • Includes standardized definitions for OA, OFA, SOA, optical elements/components/modules and abbreviated terms to ensure consistency.
  • The SOA definition (clause 3.1.3) now refers to IEC 61931.
• Scope for product specifications
  • The template sets a minimum set of parameters; product writers may add ratings, operating conditions, tests and pass/fail criteria for specific applications but should not remove the listed parameters.
• Safety and compliance
  • Contains sections addressing electromagnetic compatibility (EMC) and laser safety requirements with normative references (e.g., IEC 61000, IEC 60825‑1).

Applications - who uses IEC 61291-2:2023

• Manufacturers of OFA and SOA modules using the template to draft product specifications and datasheets.
• Test laboratories and QA teams that implement standardized test methods and acceptance criteria.
• System integrators and equipment vendors specifying amplifier performance for single‑channel fiber links, instrumentation, research or niche optical systems.
• Standards developers and procurement engineers ensuring consistency across product families and contracts.

Related standards

• IEC 61291‑1 (Generic specification)
• IEC 61291‑4 (Multichannel applications)
• IEC 61290 series (Test methods: power, gain, noise, gain ripple)
• IEC 61931 (Referenced for SOA definition)
• IEC 60825‑1 (Laser safety)
• IEC 61000 (EMC)

This standard is essential when defining measurable performance, test methods and minimum parameter sets for single‑channel optical amplifier products and specifications.
