On the news front, the 27th China International Optoelectronic Exposition (CIOE) was held at the Shenzhen World Exhibition & Convention Center from September 9 to 11. At the expo, 800G modules remain the primary shipping product, while 1.6T modules have completed verification at multiple leading companies and begun small-batch deliveries. As optical module iteration accelerates, solutions such as NPO (Near-Packaged Optics) and XPO (Plugable Co-Packaged Optics) have made large-scale appearances, with supply-demand tightness also transmitting sequentially from optical modules to upstream chips, optical fibers, and testing equipment.

Where the growth story stands

Guosheng Securities noted that with the Fed rate cut landing, macro headwinds have been temporarily lifted, allowing the optical communication industry's own high-prosperity logic to regain pricing dominance. Overall market sentiment is improving, and with Q3 major optical players expected to continue scaling up earnings, the buying opportunity for these names is gradually emerging. Furthermore, this round of passive component rally is not merely a valuation recovery but reflects a shift in fundamental logic, with Q3 sequential earnings growth expected to show strong elasticity. Therefore, investors could consider balanced allocation across major optical and passive component names, while also watching targets that have seen sufficient pullbacks and are positioned at relatively low levels.
