适用范围：This part of IEC 61290 applies to all commercially available optical amplifiers (OAs), includingOAs using optically pumped fibres (OFAs based on either rare-earth doped fibres or on theRaman effect), semiconductor optical amplifiers (SOAs) and planar waveguide opticalamplifiers (PWOAs).The object of this standard is to establish uniform requirements for accurate and reliablemeasurements, by means of the electrical spectrum analyzer (ESA) method, of the noisefigure, as defined in IEC 61291-1.The present test method is based on direct electrical noise measurement and it is directlyrelated to its definition including all relevant noise contributions. Therefore, this method canbe used for all types of optical amplifiers, including SOA and Raman amplifiers which canhave significant contributions besides amplified spontaneous emission, because it measuresthe total noise figure. For further details of applicability, see IEC 61290-3. An alternative testmethod based on the optical spectrum analyzer can be used, particularly for different noiseparameters (such as the signal-spontaneous noise factor) but it is not included in the object ofthis standard.NOTE 1 All numerical values followed by (:1:) are suggested values for which the measurement is assured. Othervalues may be acceptable but should be verified.NOTE 2 A measurement accuracy for the average noise factor of _+20 %(:1:), respectively +1 dB, should beattainable with this method (see Clause 6).NOTE 3 General aspects of noise figure test methods are reported in IEC 61290-3.
