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), semiconductor OAs (SOAs), and
waveguides (POWAs)
The object of this standard is to establish uniform requirements for accurate and reliable
measurements, by means of the optical spectrum analyzer test method, of the following OA
parameters, as defined in IEC 61291-1:
a) maximum input reflectance;
b) minimum input reflectance;
c) output reflectance.
NOTE 1 All numerical values followed by (*) are currently under consideration.
NOTE 2 The reflectance test method described in this standard does not apply to distributed fibre Raman amplifiers. The evaluation of reflectance and return loss of the distributed fibre Raman amplifiers is under consideration.
NOTE 3 The choice of methods, either the optical spectrum analyzer test method or the electrical spectrum analyzer test method, can depend on equipment availability. Normally, similar results are anticipated from both techniques.
