The organiser lists the 28th China International Optoelectronic Exposition, CIOE 2027, for 8–10 September 2027 at Shenzhen World. The event covers the optoelectronics supply chain, including communications, precision optics, lasers, infrared, sensing and displays.
Some supporting materials on the website still refer to the previous edition. The dates in this listing follow the explicit 2027 event announcement rather than an older exhibitor manual. Participation and registration arrangements remain with the organiser.
