Optical amplifiers. Test methods - Power and gain parameters - Electrical spectrum analyzer method Ingestion-build-79769 although the type of material1 Scope 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 waveguides (POWAs). NOTE The applicability of the test methods described in the present standard to distributed Raman amplifiers is for further study. The object of this standard
