YU Lin sheng 1, DONG Sheng 1, TANG Si ning 2, et al. The first domestic engineering application of Raman fiber amplifier[J]. 2003,(3):29-31. DOI: 10.13756/j.gtxyj.2003.03.008.
This paper mainly presented the application of Raman fiber amplifier (RFA) in long span SDH line and the problems required to consider and solve in product design
investigated the realization scheme and test results of ultralong span SDH optical transmission system. In addition
we discussed the problems need to be noted in practical application of RFA
and for the first time
gave the field application results of RFA in domestic 2.5 Gbit/s system over 200 km G.652 fiber. These results have positive referential value for the deployment of RFA.
