Inhalt:
We propose and optimize band-wise bidirectional S+C+L multi-band transmission in hybrid Raman-EDFA link. By counterpropagating S-band signals, we mitigate ISRS between bands and achieve uniform GSNR across bands with 27% power saving and 57% lower peak power per fibre facet compared to unidirectional transmission.
