About ECOC 2026
ECOC 2026, the 52nd European Conference on Optical Communication, takes place September 20–24, 2026 in Málaga, Spain. The conference and exhibition draw roughly 7,000 attendees from optical networking research and industry.
Who should attend
Attendees include optical networking researchers, transceiver and data center interconnect vendors, and hyperscale network architects.
Why it matters
Optics increasingly determine how far AI clusters can scale, both inside a facility and between sites. ECOC has moved steadily toward AI scale-out and scale-across fabrics and co-packaged optics, which set the bandwidth envelope for accelerated computing and the storage networks beside it.
