Optical amplifiers. Test methods - Multichannel parameters. Distributed Raman amplifier gain and noise figure not-for-sale or a functional purpose that1 Scope and object This part of IEC 61290 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 612926. A fundamental difference between these amplifiers and discrete amplifiers,
