WEINERT Fiber Optics

WEINERT Fiber Optics is a family-owned, vertically integrated fiber optic company providing complete fiber optic solutions. 

The process begins at the raw material level with in-house manufacturing of raw silica glass, followed by drawing and buffering to create spooled multimode/single-mode silica fiber. From here, we have a dedicated cabling plant stranding individual or multiple fibers into a structured cable. Lastly, the fiber/cable can be connectorized to create fiber assemblies, bundles and arrays. We have cleanroom manufacturing/sterilization to provide packaged medical devices, and digital solutions with our FiberSwitch technology.
