2025

From March 30 to April 3, 2025, the 50th Optical Networking and Communication Conference and Exposition (OFC) was held at the Moscone Center in San Francisco, USA, OFC is the largest, most professional, and most influential international event in the global optical communication field. It is hosted by the Optical Society of America (OSA), the IEEE Communications Society (IEEE/ComSoc), and the IEEE Laser and Electro-Optics Society (IEEE/LEOS), serving as the core platform for technology exchange and business cooperation in the optical communication industry. Changguang Huaxin showcased a full range of products including VCSEL, PIN, EML, and DFB at booth 1129!
