UNE-EN IEC 61290-1-2:2026

This part of IEC 61290 applies to all commercially available optical amplifiers (OAs) and

optically amplified sub-systems. It applies to OAs using optically pumped fibres (OFAs based

on either rare-earth doped fibres or on the Raman effect), semiconductors (SOAs), and planar

optical waveguides (POWAs). This document does not apply to polarization-maintaining optical

amplifiers.

The object of this document is to establish uniform requirements for accurate and reliable

measurements, by means of the electrical spectrum analyzer test method, of the following OA

parameters, as defined in IEC 61291-1, Clause 3:

a) nominal output signal power;

b) gain;

c) reverse gain;

d) maximum gain;

e) polarization-dependent gain.

In addition, this test method provides a means for measuring the following parameters:

maximum gain wavelength;

gain wavelength band.

The object of this document is specifically directed to single-channel amplifiers. For

multichannel amplifiers, the IEC 61290-10 series applies.

NOTE 1 The applicability of the test methods described in this document to distributed Raman amplifiers is for further

study.

NOTE 2 A test method for polarization-maintaining optical amplifiers is for further study.
