Cladding service to produce optical fiber preforms

Heraeus offers to convert your core rods into a full preform. There are generally two options: The large batch-size multi-ton process for telecommunication single mode fibers (RIC® process) and the very flexible outside deposition process for individual solutions.

Plasma Outside Deposition Process is used for cladding of optical fibers.

If your core rod requires cladding with a refractive index lower than that of pure fused silica, this process might be the solution for you.

This process yields highly fluorine-doped layers of glass on the substrate material, both solid and tubular. A special advantage of the process is that it is possible to clad non-circular substrates, e.g. square, hexagonal or D-shaped cores. In this case, the resulting cladding will have a non-uniform thickness.

Additionally, the fluorine content and with it the refractive index of each layer can be adjusted. This allows the production of complex refractive index profiles.

This process is very flexible and the outcome depends on many variables. For additional information please see our data sheet and we invite you to contact our experts with questions and your specific cladding task.

If you have excess core rod capacity, or are interested in using the online RIC® process in your fiber plant, the Heraeus RIC cladding service is the solution for you. It allows you to gain additional preform capacity without the need to invest in cladding glass machines. Reducing both time to market and CAPEX.

The cladding service also utilizes the high quality of our RIC® cylinders and fosters partnership. A partnership of your core rod production and fiber draw know-how and the Heraeus know-how to produce large batch high purity cladding material.
