On September 11, at the 26th China International Optoelectronics Fair, crowds surged, and “top” optical modules such as Xinyisheng, Zhongji Xuchuang, and Guangxun Technology gathered. The reporter saw on the scene that leading optical communication manufacturers have showcased the current highest-end 1.6T optical module products. The “confidentiality” level has been significantly upgraded. Many products are not allowed to be photographed or require an appointment to visit the site. Some viewers took notes on the product details. The interview found that 2025 is regarded as the first year of commercialization of 1.6T optical modules, and leading manufacturers have already begun shipping, mainly supplying overseas markets; in the domestic market, 400G/800G optical modules are still the main shipping force, and the domestic optical communication industry chain is actively expanding production and laying out advanced technology routes such as silicon light technology.
