Silicon photonics testing shift could reshape how CPO suppliers win business

The shift of silicon photonics testing to the wafer stage signals a paradigm shift in the CPO supply chain, moving from post-assembly inspection to early-stage quality control. This transformation pressures upstream foundries to enhance testing accuracy and yield management, while midstream packaging firms must restructure process coordination. Downstream system integrators face increasing demands for test data standardization. The change pushes test equipment vendors to transition from standalone products to integrated bidding models, with leading players likely to consolidate through acquisitions or strategic alliances. Geopolitical tensions, especially U.S. export controls on China, heighten supply chain fragmentation risks, with Taiwan and Hong Kong, China, facing stricter compliance scrutiny. In market dynamics, major players like NVIDIA and AMD may accelerate in-house CPO development to reduce reliance on external suppliers, while traditional module vendors may pursue vertical integration for survival. Over the next 12-24 months, test efficiency and yield will become decisive factors in CPO competition, directly shaping product competitiveness.
