QoT-Aware Adaptive Multi-Band Networking Over Hybrid Fibers Enabled by Wavelength-Selective Band Switching (Th2A.34)

Presenter: Masahiro Nakagawa, NTT Corporation

We investigate highly adaptive multi-band networking for diverse physical-layer conditions. Using our wavelength-selective band-switchable OXC prototype, we demonstrate adaptive C+L-band spectrum utilization over hybrid SMF/DSF links as link-by-link band selection can suppress nonlinear interference accumulation.
