Error in Table

In the original publication [1], there was a mistake in Table 1 as published. Instead of “

F_{n} = d d B

” this should be “

F_{n} = 5 d B

”, and instead of “

B_{W D M} = 4800 T H z

”, this should be “

B_{W D M} = 4800 G H z

”. The corrected Table 1 appears below.

Table 1. Optical fiber and system parameters.

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
