Perfect precision. Efficient performance.
Fibers, preforms and synthetic silica for advanced optical transmission technologies.
Expertise in fiber and preform design and processing: We control a fiber’s performance parameters along the complete fiber making chain starting with building the right process equipment, producing fused silica of highest purity, designing the individual preforms and finally by the subsequent drawing of the fiber.
We offer this expertise to our cable making clients, optical device manufacturers, and preform customers by supplying them with customized preforms and silica rods, standard and specialty fibers, multi-fiber-units for efficient cabling and parallel data transmission - and even process equipment and engineering on demand.
