This part of IEC 61 290 applies to all commercially available optical amplifiers (OAs) and optically amplified subsystems. It applies to OAs using optically pumped fibres (optical fibre amplifiers (OFAs) based on either rare-earth doped fibres or on the Raman effect), semiconductors (semiconductor optical amplifiers (SOAs)), and waveguides (planar optical waveguide amplifiers (POWAs)). It is specifically directed to single-channel amplifiers. Test methods for multichannel amplifiers are defined in the IEC 61 290-1 0 series.
This document establishes uniform requirements for accurate and reliable measurements of the following OA parameters, as defined in IEC 61291-1 :201 8, Clause 3:
a) nominal output signal power;
b) gain;
c) reverse gain;
d) maximum gain;
e) maximum gain wavelength;
f) maximum gain variation with temperature;
g) gain wavelength band;
h) gain wavelength variation;
i) gain stability;
j) polarization-dependent gain;
k) gain ripple (SOA only);
l) large-signal output stability;
m) saturation output power;
n) maximum output signal power;
o) maximum total output power.
NOTE 1 The applicability of the test methods described in this document to distributed Raman amplifiers is still under study.
NOTE 2 All numerical values followed by are suggested values for which the measurement is assured. Other values are acceptable if verified.
