Leo Group Co., Ltd. (002131.SZ) engages primarily in the development, manufacturing, and sale of communication cables and wires; optical fiber preforms and optical fibers; and related equipment and materials in China. The company offers a diverse portfolio of products including power transmission cables, coaxial cables, local area network cables, submarine cables, and special cables for industries such as telecommunications, electric power, transportation, and petrochemicals; it also provides optical communication products like quartz glass rods for optical fiber preforms under the brand "Lanke," silicon tetrachloride for optical fiber manufacturing, and fiber drawing towers. Leo Group operates predominantly in the domestic Chinese market with facilities in Zhejiang province and select international exports, headquartered in Yueqing City, Zhejiang, since its founding in 1995.
In recent developments, the company expanded its optical fiber segment through strategic capacity increases and technological upgrades in 2024-2025, enhancing production efficiency for high-end optical preforms amid rising demand from 5G and data center infrastructure; it formed partnerships with key telecom operators for submarine cable projects and completed a funding round via convertible bonds to support R&D in green energy cables. Leo Group underwent a minor reorganization in early 2025 to streamline its cable divisions, integrating subsidiaries focused on new energy vehicle wiring harnesses and photovoltaic cables into core operations. These initiatives position the company within the competitive telecommunications and power infrastructure segments, targeting state-owned enterprises, utilities, and emerging renewable energy markets primarily in Asia.
