Error in Table

In the original publication [1], there was a mistake in Table 1 as published. Instead of “$F_n=\mathrm{d}\mathrm{d}\mathrm{B}$” this should be “$F_n=5\mathrm{d}\mathrm{B}$”, and instead of “$B_{WDM}=4800\mathrm{T}\mathrm{H}\mathrm{z}$”, this should be “$B_{WDM}=4800\mathrm{G}\mathrm{H}\mathrm{z}$”. The corrected
