In a recent research report, Huaxi Securities noted that at the current juncture, expectations of a Federal Reserve interest rate cut have cooled, and the macro liquidity environment has marginally improved, providing a relatively friendly short-term backdrop for growth sectors. Overseas cloud providers' capital expenditure remains generally high, with Alphabet and Amazon successively raising their full-year guidance, while Microsoft's spending scale also remains elevated. The rigidity of AI infrastructure investment is clear, which continues to secure orders and performance guarantees for leading suppliers in key domestic areas such as optical modules, high-speed connections, and liquid cooling.

Wanlian Securities believes that global AI computing power infrastructure construction continues to accelerate, driving high demand for domestic and international optical interconnections. 800G is accelerating in volume, and 1.6T is gradually entering the scale deployment phase, with related order visibility continuously improving. Core domestic enterprises, leveraging their technical, capacity, and large-scale delivery advantages, are well-positioned to fully benefit from this wave of global AI computing power infrastructure construction.
