According to a research report by Industrial Securities, industry chain surveys indicate that demand for 1.6T optical modules continues to be revised upward. Overseas major clients have increased their 2026 procurement plans from 10 million units to 20 million units, primarily due to the accelerated deployment of the GB300 and subsequent Rubin platforms, as well as the rapidly growing demand for network bandwidth in AI training and inference.
