IEC 61290-1-2:2005

Overview

IEC 61290-1-2:2005 is an internationally recognized standard developed by the International Electrotechnical Commission (IEC) that defines test methods for measuring power and gain parameters of optical amplifiers using the electrical spectrum analyzer (ESA) method. This second edition updates and expands the scope to cover a wide range of commercially available optical amplifiers (OAs) including:

• Optically pumped fibre amplifiers (OFAs) based on rare-earth doped fibres or the Raman effect
• Semiconductor optical amplifiers (SOAs)
• Planar optical waveguide amplifiers (POWAs)

The standard provides precise methodologies for evaluating the performance of optical amplifiers and optically amplified subsystems, essential for ensuring quality, consistency, and interoperability in fiber optic communications.
