About this fair
CIOE 2026 brings the complete optoelectronics supply chain together in Shenzhen and is particularly relevant for buyers of components, modules and technology equipment. The organiser structures the event around optical communications, precision optics and cameras, lasers and intelligent manufacturing, infrared, sensors, new displays, AR/VR and photonic innovation. For a company sourcing Chinese manufacturers, it makes it possible to compare technical suppliers in one venue and combine the fair with factory visits along the Shenzhen–Dongguan corridor. The 2026 figures published by the organiser are forecasts and are identified as such rather than presented as final event results.

Is this trade fair worth visiting?
✓ Yes
Yes, especially if you source Electronics & Appliances, Industrial Machinery, want to compare samples in person or negotiate with several manufacturers in a few days.
— Not necessarily
Probably not if your product belongs to a different sector than Electronics & Appliances, Industrial Machinery, you already have verified suppliers and only need repeat orders, or the potential volume does not justify the trip.
Tips for visitors
Register in advance and prepare separate target lists for component suppliers and finished-product suppliers. Shenzhen makes it easy to continue with factory visits in Bao’an, Longhua, Dongguan and other nearby electronics clusters.

Getting around
Shenzhen's metro is modern and covers the whole city, including the border area with Hong Kong (Luohu/Futian station). Crossing into Hong Kong by metro plus border control takes about 45-60 minutes.
On local networks in mainland China, some international services may be restricted or unavailable. If you rely on them for work, prepare a connectivity solution that complies with current rules before travelling and do not depend on a single app. Hong Kong operates under a different internet regime.
