IEC TR 61292-9:2023 is available as IEC TR 61292-9:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC TR 61292-9:2023 which is a Technical Report, describes the characteristic features of semiconductor optical amplifiers (SOAs), including the specific features of gain ripple and polarization dependent gain (PDG). This document focuses on amplifying applications of SOAs. Other applications, such as modulation, switching and non-linear functions, are not covered. Potential applications of SOAs, such as reflective SOAs (RSOAs) for the seeded wavelength division multiplexing passive optical network (WDM-PON), are reviewed in Annex A. This third edition cancels and replaces the second edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- revised definitions for SOAs in 3.1;
- added more theoretical background on gain ripple measurements using amplified spontaneous emission (ASE) spectrum in 4.3;
- removed the formerly preferred set-up for output power and PDG measurements in Clause 5.
