About WEINERT Industries
WEINERT Industries AG is a technology manufacturer specialized in fiber optics, headquartered in Föritztal (Thuringia). The company manufactures specialty optical fibers – including radiation-hardened, temperature-resistant and polymer fibers (POF, PCF, HPCS/PCS) – from quartz glass and plastic, from these specialty and standard fiber optic cables (including marine, military, sensor, hybrid and CPR cables) as well as fiber bundles, assemblies and optical components such as splitters, optical switches, cross-section converters, probes and vacuum feedthroughs. The value chain ranges from raw materials (preforms, rods, capillaries, SQ fused silica) through in-house fiber and cable production to assembly and the assembly of medical devices and optical switches. Customers come from industries such as automotive, data communications, energy, automation, medical technology, shipbuilding, defense, aerospace, laser technology and research; applications extend to gravitational wave sensors and ISS experiments for NASA/JPL. In addition to the German site, the group maintains production in Jiangsu (China) and Romack Fiber Optics in Williamsburg (USA), and is acquiring CBI Electric Telecom Cables in Brits (South Africa).

Materials and Processes
Fused Silica / SQ quartz glass
Base material for preforms, specialty optical fibers, fiber bundles and optical components.
Polymer Optical Fiber
Plastic fiber for cost-effective industrial cables with typical lengths of around 50 m at 100 Mbit/s.
Polymer Clad Fiber
Plastic-clad fiber for industrial applications with reach up to approx. 200 m at 100 Mbit/s.
HPCS and PCS fibers
Hard Polymer Clad and Polymer Clad Silica fibers for media-resistant industrial cables.
Radiation-hardened multimode fiber 50/125 and 62.5/125
For data transmission in nuclear power plants and aerospace under high gamma radiation, tested to MIL-PRF-49291.
Radiation-hardened singlemode fiber 9/125
Singlemode fiber for radiation-exposed environments, compatible with standard networks.
FRNC outer sheath (halogen-free, flame-retardant)
Halogen-free, flame-retardant sheath for marine and CPR cables with functional integrity in the event of fire.
PUR sheathing
Industrial-grade polyurethane sheathing for flexible, media-resistant cables, e.g. in the E-chain.
