2020 OFC Demo Zone

Organizers: Filippo Cugini, CNIT, Italy; Josue Kuri, Google, USA; Hideaki Furukawa, NICT, Japan

The OFC Demo Zone features live demonstrations of research projects and proof-of-concept implementations in the space of optical communication devices, systems and networks.

Such demonstrations take place in a dedicated booth, and are shown to small groups favoring a very interactive format with real time exchanges between attendees and demo presenters. Demonstrations are typically executed on demand, and may involve a combination of on-site and remote equipment.
