What Weinert does

WEINERT Industries AG is a privately held German Aktiengesellschaft headquartered in Föritztal, Thuringia, specializing in optical fiber, cable, component, and assembly technologies for industrial customers. The company controls the full vertical chain from synthetic quartz glass and preforms (via subsidiary j-plasma GmbH in Jena, with 40+ years of quartz glass tradition) through specialty fiber drawing (Berlin), cable extrusion and assembly (Roth, Sonneberg), to finished fiber optic assemblies, with additional manufacturing capacity in Changshu, China, and Brits, South Africa. Its product portfolio spans ambient, radiation-hard, high-temperature, polymer, and photonic crystal fibers; CPR-, UL-, DNV GL-, MIL-, and NPP-certified cables; the proprietary LE.X.CO compound cable; fiber bundles; optical splitters, switches, arrays, and probes; plus fiber manufacturing and engineering services. The company sells to eight named vertical markets including automotive, data communications, energy and infrastructure, factory automation, healthcare, optical metrology, marine/maritime, and transportation.

WEINERT operates a direct enterprise field sales model with regional teams covering Europe, the Americas, Greater China, India, Southeast/East Asia, the Middle East, and Africa, supported by localized manufacturing and a multilingual corporate website. Revenue is generated primarily through customized hardware sales on a quote-based, project-specific pricing model with no public pricing disclosed. Recent inorganic expansion includes the 2022 acquisition of BizLink Group's fiber optic assembly assets in China and the 2023 agreement to acquire CBI Electric Telecom Cables in South Africa, while a January 2025 entry into the EFRE-funded AreaLight project signals diversification into UVC disinfection light sources. Leadership is anchored by CEO Andreas WEINERT, suggesting founder-family control, and the company operates without disclosed external private equity or venture capital backing.
