Fiber per preform [km]
Since the beginning of optical fiber production, there hasbeen a steady growth in the size of preforms being manu-factured by Heraeus' customers. As single mode preformsizes have increased, so has the amount of fiber beingdrawn from these preforms. With the Rod-in-Tube (RIT)technology, our largest overclad tubes facilitated preformsizes up to 900 km. In keeping with our commitmentto “The Evolution of Size,” our Rod-in-Cylinder (RIC®)technology can result in preforms equivalent to fiberlengths of 10,000 km. These large preforms can increaseour customers' profitability and significantly improve theirmanufacturing costs and efficiencies without compromisingproduct quality.

Technical benefits
Using Heraeus' high purity F300 jacketing material ensures the production of world class optical fiber. Since the F300 cladding material is essentially free of OH, low and zero water peak fibers can be readily made using the RIC®
process. In production, benchmark break rate levels are achieved thanks to the purity of our material, leading to superior product performance.
RIC® cylinders are fabricated using CNC-controlled lathes resulting in outstanding geometrical performance. The ground outer surface of the cylinders is suitable for direct fiber draw and results in superior fiber geometries.

How to get started
Heraeus possesses extensive RIC® process experience. Therefore, we can support fiber manufacturers in the implementation of the RIC® technology and can tailor it to your company's fiber manufacturing processes. As a preliminary step, the feasibility of the RIC® technology can be demonstrated by overcladding your core rods at our Offline RIC® facility. These RIC® preforms can then be drawn into fiber and qualified at your facility.
About us
Heraeus is the key global supplier of high purity synthetic fused silica products for optical fiber manu -facturing. We have been a reliable partner in the world telecommuni cations industry since 1976.
