Preform service for telecommunication fibers

Heraeus has been a driving force in the evolution of preform sizes. With the RIC® process, we can turn your core rod into a full preform. The core rod with the correct b/a is placed into a cylinder and in a consecutive hot forming step the cylinder is collapsed onto the core rod.
We currently supply single mode preforms with an outer diameter of up to 230 mm. We are very flexible in preform size, providing the ideal size for your draw tower.

Heraeus large scale preforms allow for a most economic fiber draw, by increasing productivity as these preforms can run multiple days.

For details about the available fiber types and limitations, your draw tower may have please contact us.
