Huawei builds its own optical module factory

Huawei produces a wide range of optical modules through its HISILICON division, supported by domestic chip manufacturing and advanced R&D facilities.Manufacturing Facilities and TechnologyHuawei's optical module production is anchored by the Wuhan Huawei Optical Factory, its first domestic optical chip factory, covering 208,900 square meters. This facility enables Huawei to produce optical chips independently, without relying on U.S.-origin technology, achieving “comprehensive de-beautification” in its supply chain . The factory initially focused on 45nm chipsets using 28nm lithography, with plans to advance to sub-20nm processes, supporting high-speed optical module production . This capability allows Huawei to manufacture laser chips for photoelectric signal conversion, essential for 5G, IoT, AI, and optical communication networks .HISILICON Optical Module R&D and ProductionHuawei's HISILICON division (formerly Huawei Integrated Circuit Design Center) is responsible for the R&D and manufacturing of optical modules. HISILICON operates from the Wuhan Research Institute and HISILICON Optoelectronics Co. in the East Lake Hi-Tech Zone, with multiple R&D centers across China, Singapore, South Korea, Japan, and Europe . The company produces a broad range of optical modules, including:Datacom Transceivers for data centersTelecom Transceivers for metro networksFTTx Transceivers for broadband accessWireless Transceivers for mobile networksTransmission Transceivers for long-haul and high-speed optical linksWavelength Management (WSS) modules for multi-dimensional optical switching HISILICON has achieved 100G optical module chip technology and ranks among the top four global optical module suppliers, contributing significantly to global optical communication networks .Product PortfolioHuawei offers a comprehensive range of optical modules for various applications:StarryLink pluggable modules for data center networks, providing flexible plug-and-play solutions PON SFP modules for GPON, XG-PON, XGS-PON, and 50G-PON broadband access, supporting transmission distances up to 60 km and high optical budgets Modules optimized for cloud computing, ultra-wideband networks, and high-speed coherent optical interconnects These modules are widely deployed by ISPs, telecom operators, and enterprise networks, ensuring scalability and future-ready connectivity.Market PositionHuawei is a leading global vendor in the optical module market, holding a significant share alongside other major players like Coherent and Cisco. The global optical module market is projected to grow from $8.94 billion in 2024 to $20.22 billion by 2032, driven by data center bandwidth demands, 5G deployment, and cloud computing expansion . Huawei's continuous innovation in silicon photonics, co-packaged optics, and high-speed optical modules positions it as a key contributor to this growth .SummaryHuawei's optical module production combines domestic chip manufacturing, advanced R&D through HISILICON, and a diverse product portfolio for data centers, telecom, and broadband networks. Its technological independence and global market presence make it a major player in the optical communications industry, capable of supporting high-speed, scalable, and future-ready network deployments .
