Analytical results on channel capacity in uncompensated optical links with coherent detection (vol 19, pg B438, 2011)

We recently realized that there was an error in the expression of the non-linear interference power in case of distributed amplification reported in [G. Bosco Opt. Express 19 B438 (2011)] Eq. (4). In this erratum we correct the error in Eq. (4) and in all related equations and plots in [G. Bosco Opt. Express 19 B438 (2011)]. (C) 2012 Optical Society of America
