Abstract The main goal of this paper is to demonstrate the advantages of a hybrid RamanEDFA optical signal amplification solution over the use of conventional EDFA amplifiers. The most promising solution of hybrid amplification is supplementing the existing discrete amplifier with a distributed Raman amplifier, as it not only can broaden and equalize the gain spectrum, but it also can increase the optical signal-to-noise ratio of the signal at the output of the amplifier and can provide higher level of amplification. The obtained results have shown, that the implementation of the hybrid solution has allowed to increase the optical single-to-noise ratio by at least 1.7 dB in all of the channels.
