Abstract: We find evidence that low-OSNR operation causes substantial penalty on system maximum reach due to non-linearity generated by ASE noise and due to signal-power conversion into non-linear noise. Neglecting these effects may lead to a quite substantial performance prediction error.<br />Comment: A prior version of this paper has been accepted at the ECOC 2014 conference. This version contains some important corrections and updates, with respect to the ECOC 2014 paper. Also, the prior pblished arXiv version had a font problem in the pdf file, so that some brackets would not show up in formulas. This new version is identical, except that it fixes the font problem
