Product information
What is Zhongji Innolight Co., Ltd. (300308.SZ)?
Zhongji Innolight Co., Ltd. is a Chinese optical communications company whose registered address is in Longkou, in Shandong province. Its roots lie in Longkou Zhongji Electrical Machinery, founded in 2005, and InnoLight Technology, founded in Suzhou in 2008; the two completed a restructuring in 2017, and the present name came out of it. The shares began trading on the ChiNext board of the Shenzhen Stock Exchange in April 2012, and the stock code is 300308. In 2026 the company also listed H shares on the Main Board of the Hong Kong Stock Exchange.
The company presents itself as a global supplier of high-speed optical interconnect solutions. An optical transceiver is a module that turns electrical signals into light so that servers and switches can exchange data; the company's products are made for cloud and AI infrastructure, coherent transport networks and mobile networks. It also says it is investing in next-generation architectures such as LPO and NPO, and a manufacturing site in Thailand came into operation in 2022.
Those following the stock usually watch the pace of cloud and AI infrastructure investment, export and technology restrictions, raw material and chip supply, and the yuan-dollar exchange rate.
