IEC 61290-1-2:2026

Overview

IEC 61290-1-2:2026 specifies test methods for measuring power and gain parameters of optical amplifiers (OAs) using the electrical spectrum analyzer (ESA) method. Developed by the International Electrotechnical Commission (IEC), this standard is applicable to all commercially available optical amplifiers and optically amplified sub-systems, including those utilizing optically pumped fibres (rare-earth doped or Raman effect), semiconductors (SOAs), and planar optical waveguides (POWAs). Polarization-maintaining optical amplifiers and multichannel amplifiers are addressed under related or future standards.

By defining uniform testing procedures and requirements, IEC 61290-1-2:2026 ensures repeatability, accuracy, and reliability in the measurement of key OA performance parameters, facilitating interoperability and quality assurance in fiber optic networks.

Key Topics

• Scope and Applicability: Covers single-channel OAs in commercial applications; not intended for distributed Raman or polarization-maintaining amplifiers.
• Test Parameters:
  • Nominal output signal power
  • Gain and reverse gain
  • Maximum gain
  • Polarization-dependent gain
  • Maximum gain wavelength and wavelength band
• Test Method: Describes a uniform process using an electrical spectrum analyzer to measure and calibrate amplifier characteristics.
• Required Equipment: Outlines specifications for optical sources, power meters, optical couplers, isolators, attenuators, polarization controllers, detectors, and the electrical spectrum analyzer.
• Procedure: Includes step-by-step methods to set up the test, calibrate equipment, conduct measurements under various operating conditions, and minimize measurement uncertainty.
• Calculation: Provides formulas for determining output signal power, gain, and polarization-dependent gain.

Applications

IEC 61290-1-2:2026 is essential for:

• Manufacturers: Ensures consistent, comparable specifications for optical amplifiers by providing standardized testing methods.
• Telecommunications and Data Centers: Facilitates the selection and deployment of optical amplifiers in long-haul, metro, and access networks.
