Dual order bidirectional Raman amplification are preferred over first order counterpart due to their lower signal power variation (SPV) and consequently superior optical signal to noise ratio (OSNR) performance. These benefits are counteracted by the disadvantage of relative intensity noise (RIN) transfer from forward pumps to signal. In this work, we demonstrate a forward pumping scheme which uses a broadband 1st order seed and 2nd order bidirectional pumping. This configuration performs better than other conventional 1st order forward pumped schemes, reducing the signal RIN to a level comparable with backward only pumping.
