39、TRODUCTION This part of IEC 61290 is devoted to the subject of optical amplifiers. The technology of optical amplifiers is still rapidly evolving, hence amendments and new additions to this standard can be expected. Each abbreviation introduced in this standard is generally explained in the text the
40、 first time it appears. However, for an easier understanding of the whole text, a list of all abbreviations used in this standard is given in Clause 3.

41、 and object This part of IEC 61290 applies to commercially available optical amplifiers (OAs) such as optical fibre amplifiers (OFAs), semiconductor optical amplifiers (SOAs) and planar waveguide amplifiers (PWOAs) as classified in IEC 61292-3. The object of this standard is to establish uniform req
42、uirements for accurate and reliable measurements, by means of the optical spectrum analyzer (OSA) test method, of the following OA parameters, as defined in IEC 61291-1: a) signal-spontaneous noise figure; b) forward amplified spontaneous emission (ASE) power level. The methods described in this par
43、t of IEC 61290 apply to single-channel stimulus only. Two alternatives for determining the signal-spontaneous beat noise are possible, namely the ASE direct interpolation technique (DI) and the polarization nulling with interpolation technique (PN). The accuracy of the DI technique will suffer when
44、the slope of the OA spectral ASE curve has large wavelength dependence, as in the case of an OA with an internal narrowband ASE suppressing filter. The accuracy of the DI technique degrades at high input power level due to the spontaneous emission from the laser source(s). Annex A provides guidance
45、on the limits of this technique for high input power. NOTE 1 All numerical values marked with () are suggested values for which the measurement is assured. Other values may be acceptable but should be verified. NOTE 2 General aspects of noise figure test methods are reported in IEC 61290-3. 2 Normat
