IEC 61290-1:2014

Overview

IEC 61290-1:2014 is an international standard published by the International Electrotechnical Commission (IEC) that defines test methods for measuring the power and gain parameters of optical amplifiers (OAs). This standard applies broadly to commercially available OAs including those based on optically pumped fibres (OFA), semiconductors (SOA), and waveguides (POWA). It sets uniform and precise requirements for accurate and reliable measurement of key amplifier parameters, ensuring consistency and comparability across products and systems in optical communications and photonics industries.

The scope of IEC 61290-1:2014 focuses on single-channel optical amplifiers, providing guidelines on test procedures to evaluate signal power, gain characteristics, and stability under varying conditions. For multichannel optical amplifiers, the related IEC 61290-10 series covers relevant test methods.
