On the news, it is reported that "this year's order volume has expanded rapidly than expected" and "orders have been scheduled to next year." Such voices are heard endlessly in front of the 1.6T booth at the 27th China International Optoelectronics Expo in 2026. At this Optical Expo, "1.6T" has completely reached the "C position" and has become a "must-exhibit highlight" in almost every link of the industrial chain, from modules to engines, chips, demodulators, optical fibers, materials, and test equipment.
