Real-Time Demonstration of an SDN-Based Gridless Routing/Protection over a Remote Optically Pumped Passive Optical Add/Drop Network

We demonstrated a passive optical add/drop network for full C-band transmission over four passive nodes and 204.5 km of fiber using real-time 100/200-GbE transponders. We also demonstrate SDN-enabled wavelength protection, and system compatibility with superchannel transmision.
