Accelerating 800G/1.6T adoption. LightCounting forecasts global optical module market reaching $37 billion by 2029, with 800G shipments doubling YoY to 18-19.9 million units in 2025. 1.6T modules are expected to enter commercial deployment with 2.5-3.5 million unit demand. 3. Early positioning for "Spring Rally" earnings catalysts. Guosen Securities highlights January as a key window for AI computing/storage chain earnings surprises, with multiple hard-tech thematic fund approvals potentially accelerating sector recovery.
Looking ahead to 2026, Industrial Securities projects overseas computing power entering an "afterburner" phase. Despite three years of high growth, infrastructure investment remains robust with Blackwell GPUs driving data center acceleration and Rubin GPUs progressing smoothly. 1.6T modules may dominate 2026 demand, sustaining high earnings growth for sector leaders.
