Scope and object
This part of IEC 61290-3 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-spontane
IEC 61290-3-1 describes a measurement method, using an optical
spectrum analyzer, OSA, for the signal-spontaneous noise factor
Fsig−sp but does not describe a method for measuring
Fsp-sp. IEC 61290-3-2 describes a measurement method,
using an electrical spectrum analyzer (ESA), for the total noise
factor Fsp-sp + Fsig-sp. However, this method
does not allow Fsp-sp to be measured separately, and therefore does
not provide a means of directly quantifying the effect of
spontaneous-spontane
Two measurement methods are provided for the ratio of the signal output power to the total ASE power. The first method uses an OSA, while the second method uses a bandpass filter and an optical power meter.
