Reference optical filter sets are described in Annex A. Keywords: test and measurement procedures of the wavelength channel tuning time

IEC 61290-10-5:2014 applies to distributed Raman amplifiers (DRAs). DRAs are based on the process whereby Raman pump power is introduced into the transmission fibre, leading to signal amplification within the transmission fibre through stimulated Raman scattering. A detailed overview of the technology and applications of DRAs can be found in IEC TR 61292-6. The object of this standard is to establish uniform requirements for accurate and reliable measurements, using an optical spectrum analyser (OSA), of the following DRA parameters: - channel on-off gain; - pump unit insertion loss; - channel net gain; - channel signal-spontaneous noise figure. Keywords: Raman amplifiers (DRAs), optical spectrum analyser (OSA)

IEC 62149-9:2014 covers the performance specification for seeded reflective semiconductor optical amplifier (RSOA) transceivers used for the fibre optic telecommunication and optical data transmission applications. The performance standard contains a definition of the product performance requirements together with a series of sets of tests and measurements with clearly defined conditions, severities, and pass/fail criteria. The tests are intended to be run on a 'once-off' basis to prove any product's ability to satisfy the performance standard's requirements. A product that has been shown to meet all the requirements of a performance standard can be declared as complying with the performance standard, but should then be controlled by a quality assurance/quality conformance program. Key words: seeded reflective semiconductor optical amplifier (RSOA) transceivers

IEC 61290-3-3:2013 applies to all commercially available single channel optical amplifiers (OAs), including OAs using optically pumped fibres (OFAs) based on either rare-earth doped fibres or on the Raman effect, semiconductor optical amplifier modules (SOA modules) and planar optical waveguide amplifiers (POWAs). More specifically, it applies to single channel OAs placed before optical receivers, where there are no optical bandpass filtering elements placed between the OA and the receiver. The object of this part of IEC 61290-3 is to establish uniform requirements for accurate and reliable measurement of the ratio of the signal output power to the total ASE power generated by the OA in the optical bandwidth of the receiver. This quantity is a measure of the spontaneous-spontaneous beat noise at the receiver, and is correlated to the spontaneous-spontaneous noise factor of the OA, Fsp-sp, as defined in IEC 61290-3 and IEC 61291-1.
