The 22nd CIOE 2020 (China International Optoelectronic Exposition) took place in Shenzhen, China, from September 9th to 11th. The fair hosts 3,000 exhibitors and more than 60 seminars, forums and networking activities in the field of optoelectronic components, devices and systems. Due to the ongoing travel restrictions in connection with the corona pandemic, the Lumics team was unfortunately not able to attend the trade fair in person. However, through the long-standing sales partner in China, Connet Fiber Optics Co. Ltd. from Shanghai, the Lumics portfolio was successfully presented at the German pavilion. Most of the visitors at to the booth were interested in applications such as welding or medicine and analysis, or were just looking for special single-mode wavelengths.
