The International Electrotechnical Commission (IEC) has published IEC 61290-10-5:2014, “Optical Amplifiers – Test Methods – Part 10-5: Multichannel Parameters – Distributed Raman Amplifier Gain and Noise Figure.” The new standard is available in the IEC’s webstore here.
“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)”
