Abstract

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.

Capacity limit vs. launch power per channel at different system lengths with ideal distributed-amplification with F=5 dB, Ls =100 km. Assumptions: UT and PM-Gaussian constellation, 125 channels at 32 GBaud, channel spacing equal to symbol-rate, resulting in a total optical bandwidth of 4 THz. Dashed lines: Shannon limit - Eq. (7). Solid lines: non-linear capacity limit - Eq. (9),(10).
