Which company makes Huawei s optical modules

Huawei's optical modules are typically manufactured by leading Chinese optical component suppliers such as HiSilicon, Innolight, Eoptolink, Hisense Broadband, and other certified vendors.Key OEM PartnersHuawei does not produce all optical modules in-house; instead, it relies on a network of OEM manufacturers. The main suppliers historically and currently include:HiSilicon – Huawei's in-house semiconductor and optical module design arm, producing high-end modules including coherent DWDM transceivers .Innolight Technology – A major Chinese optical module supplier, often producing modules for Huawei and other networking companies .Eoptolink – Provides a range of optical transceivers and has been listed among Huawei's certified module suppliers .Hisense Broadband – Another Chinese vendor supplying modules compatible with Huawei equipment .Other Chinese suppliers – Companies such as Xutron, Optical Xun Technology, Xin Yisheng, Huagong Zhengyuan, and Solstice Optoelectronics have been included in the global top 10 optical module suppliers and are potential OEM partners for Huawei .Certification and LabelingHuawei certifies optical modules for its switches and networking equipment. Certified modules carry the HUAWEI label, but the Vendor Name field may still display the original manufacturer . This means that while Huawei ensures functionality and quality through certification, the physical manufacturing is often done by these OEM partners. Certification covers modules such as 40GE, 100GE, and high-speed AOC cables, ensuring compatibility and performance standards.Market ContextThe global optical module market has shifted significantly toward Chinese suppliers. Many Japanese and U.S. vendors have exited the market, while Chinese companies, including those supplying Huawei, have expanded their production domestically or in Asia . Huawei also invests heavily in local supply chains to secure IC chips and other components, especially given restrictions on access to the latest CMOS technology . In summary, Huawei's optical modules are primarily OEM-manufactured by leading Chinese optical module suppliers, with Huawei performing certification and quality verification to ensure compatibility with its networking products.
