- Wuhan Changjin Photonics Technology Co., Ltd. is a China-based high-technology enterprise primarily engaged in the research, development, manufacturing, and distribution of specialty optical fibers, optical preforms, and associated photonic solutions for industrial and high-reliability optical applications. Founded in 2012 and headquartered in Wuhan, Hubei Province, China, within the East Lake High-Tech Development Zone (Optics Valley of China), the company operates specialized production and testing facilities, serving equipment manufacturers and research institutions across the advanced laser manufacturing, optical telecommunications, defense, medical, and sensing sectors. The company's core product portfolio encompasses a comprehensive range of active and passive specialty optical fibers categorized as follows: rare-earth-doped active optical fibers, including single-mode and multi-mode ytterbium-doped fibers (Yb-doped), erbium-doped fibers (Er-doped), erbium-ytterbium co-doped fibers (Er/Yb co-doped), and thulium-doped fibers (Tm-doped) engineered for high-power continuous-wave and pulsed fiber lasers, optical amplifiers, and LiDAR systems; passive optical fibers and matching transmission products, including large-mode-area (LMA) passive fibers, photosensitive fibers, single-clad and double-clad pump energy transmission fibers, and high-power laser delivery fibers; photonic crystal fibers (PCF), comprising hollow-core photonic crystal fibers, dispersion-compensating fibers, and high-nonlinearity microstructured fibers; polarization-maintaining (PM) specialty fibers, including PM rare-earth-doped active fibers and PM passive fibers designed for fiber-optic gyroscopes, inertial navigation, and coherent optical communications; and high-reliability functional fibers, including radiation-resistant active and passive fibers developed for aerospace, space-based laser communications, and nuclear instrumentation. Complementing its manufactured products, the company provides customized fiber preform design, specialty fiber drawing, precision optical characterization, and OEM/ODM engineering services. In recent corporate developments, Wuhan Changjin Photonics Technology Co., Ltd. completed its initial public offering (IPO) and listed its Class A shares on the Science and Technology Innovation Board (STAR Market) of the Shanghai Stock Exchange under the ticker 688635 in May 2026. The company utilized proceeds to fund the construction and operational commissioning of its new high-performance specialty optical fiber industrialization base and central research and development facility in Wuhan, substantially scaling its preform fabrication and fiber drawing capacity following the facility's structural completion in mid-2025. In product innovation, the company expanded its commercial offerings with the rollout of next-generation ultra-wideband L-band erbium-doped fibers designed for 400G and 800G optical backbone networks, ultra-high-power ytterbium-doped fibers supporting single-fiber output exceeding 6 kilowatts for heavy industrial laser cutting and welding, and space-grade radiation-hardened doped fibers for satellite optical payloads. Operationally, the company has reinforced strategic supply partnerships with major laser systems integrators and optical module vendors—including Raycus, Maxphotonics, JPT Opto-electronics, and Accelink Technologies—while advancing its technical and manufacturing infrastructure through wholly owned operating subsidiaries, including Wuhan Changjin Xianfeng Optoelectronic Technology Co., Ltd. and Wuhan Topu Optical Technology Co., Ltd.
