At LEONI Fiber Optics, a subsidiary of the renowned LEONI Group, we pride ourselves on delivering exceptional preforms crafted from highly pure fused silica materials. These preforms serve as the foundational element in the creation of both high-performance special fibers and standard fibers, tailored meticulously to meet customer specifications. Our expertise in developing these preforms ensures they are perfectly suited for a wide range of applications, whether it's for transmitting high data rates or facilitating high-power laser transmission.

Our process begins with a detailed customization of the waveguide design, aligning it with your specific requirements from prototype to series production. We meticulously specify the preform design and configuration, focusing on the core profile—be it step-index or graded-index—and selecting the appropriate dopant options such as Germanium, Fluorine, Boron, or Rare-earth elements. This attention to detail ensures the achievement of the desired numerical aperture.

Additionally, we offer precise control over the geometry of the preform, shaping both the core and cladding to suit application-specific assemblies. Quality is at the heart of everything we do. Each preform undergoes stringent quality monitoring, ensuring that it meets the highest performance standards during the fiber drawing process. This commitment to quality guarantees that the preforms we produce deliver optimal performance in even the most demanding applications.

By utilizing advanced production techniques, such as our proprietary MCVD process for graded-index and step-index fibers, we ensure that the preforms meet the specified fiber performance properties. With our innovative approach, LEONI Fiber Optics offers graded-index preforms for high-performance multimode fibers in the 50/125 and 62.5/125 designs. These preforms are produced using the cutting-edge MCVD technique, ensuring consistency and reliability. On request, we can provide graded-index preforms with a handle, facilitating easy fixation in the drawing tower.

Our dedication to precision and performance ensures that every preform we produce is of the highest quality, perfectly poised to meet the evolving needs of the fiber optics industry.
