What did our visitor say ?

This year is a very special year for everyone. Even under the dual influence of the political environment and the epidemic, CIOE has withstood them and expanded its influence in terms of exhibitor number, exhibit profile, visitor number and buyers’ quality. CIOE once again successfully completed the annual leading event in the optoelectronics industry. In the future, we also hope to further deepen exchanges and cooperation with CIOE in the optoelectronic industry chain.

—— Mr. Ren, Chief Expert, Huawei



After CIOE’s move to the new exhibition center, the scale was much larger than before. This year, affected by the epidemic and the international situation, the progress of many industries has slowed down. Fortunately, the CIOE‘s platform still help us to find what we targeted products. Via CIOE, I have met many partners, and also got to know many potential suppliers. I sincerely wish that CIOE will become better!

—— Mr. Liu, Sourcing Manager, Goertek



As the world's most influential optoelectronic event, CIOE has been improving itself for 22 years and it now has become a platform covering the entire industry chain of China's optoelectronics.
