IEC 61290-1:2022

Overview

IEC 61290-1:2022 - Optical amplifiers - Test methods - Part 1: Power and gain parameters is the 2022 edition of the IEC international standard that defines uniform, repeatable test methods and reporting for single-channel optical amplifiers (OAs) and optically amplified subsystems. It applies to optical fibre amplifiers (rare-earth doped and Raman), semiconductor optical amplifiers (SOAs) and planar optical waveguide amplifiers (POWAs). This edition updates the 2014 standard, adds gain ripple as a specified parameter, and replaces the term “measurement accuracy” with measurement uncertainty.

Key topics and technical requirements

• Scope: Single-channel OAs (multichannel methods are in the IEC 61290-10 series). Applicability to distributed Raman amplifiers is under study.
• Measured parameters: nominal output signal power, gain, reverse gain, maximum gain and its wavelength, gain variation with temperature, gain wavelength band and variation, gain stability, polarization-dependent gain, gain ripple (SOA only), large-signal output stability, saturation output power, maximum output signal power and total output power.
• Test methods: The standard requires following one of three measurement procedures:
  • Optical Spectrum Analyzer (OSA) method (IEC 61290-1-1)
  • Electrical Spectrum Analyzer (ESA) method (IEC 61290-1-2)
  • Optical power meter with bandpass filter method (IEC 61290-1-3)
• Measurement practice: Defines step sizes (e.g., wavelength steps < 1 nm near ASE peak where applicable), monitoring procedures for polarization and temporal instabilities, and guidance on reporting measurement uncertainty. Numerical values marked (‡) are suggested assurance values; other values may be acceptable if verified.
• New/changed elements: formal test and report procedures for gain ripple; emphasis on uncertainty quantification.

Practical applications

• Product characterization and datasheet validation for OAs (OFA, SOA, POWA)
• Manufacturing quality control and production testing
• R&D and performance benchmarking across wavelength and temperature
• Procurement specifications and interoperability verification for optical systems
• Regulatory and conformity testing where standardized measurement methods are required

Who should use this standard

• Component and subsystem manufacturers (fiber amplifier, SOA, POWA vendors)
• Test laboratories and QA teams performing optical amplifier measurements
• System integrators and telecom operators specifying amplifier performance
• Standards and regulatory bodies referencing consistent test procedures
