What is the domestic demand for optical modules

Domestic demand for optical modules in China is rapidly increasing, driven by AI computing, 5G deployment, and data center expansion, with localization rates for key components steadily rising.Market DriversThe domestic demand for optical modules is primarily fueled by AI and cloud computing growth, which require high-speed, low-latency data transmission in hyperscale data centers . Large-scale 5G network deployment further accelerates demand, particularly for 25G and 100G optical modules used in fronthaul and midhaul networks . Government initiatives, such as the "East Data West Computing" project, provide policy support that encourages domestic production and infrastructure expansion .Production and LocalizationChina has made significant strides in domestic production of optical modules. For low-speed modules (2.5G/10G), localization rates have reached 90% and 60%, respectively, while medium- and low-speed chips below 10G exceed 65% localization . Core chip production, including 25G/50G DFB and EML lasers, has achieved over 50% self-sufficiency, although high-end DSP chips remain largely imported . Domestic manufacturers like ETU-LINK have established full production lines with on-time delivery rates above 99%, supporting the growing domestic demand .Market Size and GrowthThe global optical module market is projected to grow from $13.2 billion in 2022 to $35.8 billion by 2030, with China accounting for over 70% of global manufacturing . Domestic demand is expected to mirror this growth due to hyperscale data center expansion, AI workloads, and 5G infrastructure, with high-speed modules (100G and above) seeing the fastest adoption .Technological AdvancementsTechnological breakthroughs in domestic optical modules include 100G QSFP28 ZR4 80KM modules and 25G SFP28 BIDI 80km modules, which offer high performance comparable to international standards while reducing costs and power consumption . These innovations are critical for meeting the bandwidth and latency requirements of AI, cloud computing, and 5G networks.SummaryIn summary, domestic demand for optical modules in China is surging, driven by AI, cloud computing, and 5G deployment. Policy support, technological advancements, and increasing localization of production are enabling domestic manufacturers to meet this demand efficiently, particularly for high-speed and cost-effective modules used in data centers and telecom networks .
