OFC is about to celebrate its 50th anniversary. In today's show, Gareth Spence talks to LightCounting analyst and Gazettabyte editor Roy Rubenstein, along with Adtran's leader of advanced technology, Jörg-Peter Elbers. Together, they look back on five decades of optical innovation, explore what's next for the industry and discuss hot topics for OFC 2025 – including why this year's rump session has an alien vibe.
