Domestic optical modules are reliable

Domestic optical modules have become increasingly reliable, with performance approaching international standards and strong supply chain support.Technological MaturityDomestic optical modules have achieved significant technological breakthroughs, progressing from low-speed to high-speed applications. For example, the localization rate of 2.5G and 10G optical chips has reached 90% and 60% respectively, while high-speed modules such as 100G QSFP28 ZR4 80KM demonstrate performance comparable to top-tier international products, achieving 80 km transmission with power consumption below 5.5W . Innovative designs like the 25G SFP28 BIDI 80km module reduce cabling costs and are recognized as leading domestic technologies for 5G fronthaul networks .Supply Chain and Production ReliabilityDomestic manufacturers, such as ETU-LINK, have established full production lines and robust supply chains, achieving on-time delivery rates exceeding 99% . The domestic industrial ecosystem now supports comprehensive services from chip selection to module integration and scenario adaptation, enhancing reliability and responsiveness for network operators .Core Component DevelopmentSignificant progress has been made in domestic optical module chips, including laser chips (DFB and EML), detector chips, driver chips, TIA chips, and DSP chips. Mass production of 25G, 50G, and some 100G-level chips has been achieved, and high-speed DSP chips are gradually being localized . While some high-end chips above 400G still rely on imports, ongoing R&D is steadily improving domestic capabilities.Future OutlookThe domestic optical module industry is moving toward higher speeds (800G and beyond), independent control of high-end chips, and expansion into new scenarios such as automotive optical modules and satellite internet . With continued technological innovation and industry collaboration, domestically produced optical modules are expected to maintain high reliability and increasingly compete on a global scale.ConclusionOverall, domestic optical modules are reliable for most current applications, including 5G networks and data centers, with performance, supply chain stability, and technological maturity steadily improving. While ultra-high-speed modules still face some dependency on imported components, domestic solutions are increasingly cost-effective, high-performing, and suitable for critical communication infrastructure .
