Impact of WDM-Band Drop on $\mathrm{S}+\mathrm{C}+\mathrm{L}$ Multi-Band Optical Transmission Systems

We experimentally assess the impact of different band drops on the performance of
$\mathbf{S}+\mathbf{C}+\mathbf{L}$
multi-band optical transmission systems. We also present the digital twin of our experiment that quantifies the different noise contributions affecting the system performance in detail. Our results highlight how the L band is largely affected due to the lack of ISRS-induced power transfer when the S band is missing.
