Description
LEONI's subsidiary, j-fiber, is a leader in developing and producing high-quality preforms using highly pure fused silica materials. These preforms serve as the foundation for manufacturing high-performance special fibers and standard fibers, tailored to meet customer specifications. Whether your objective is to facilitate the transmission of high data rates or to support high-power laser transmission, LEONI offers customizable waveguide designs to suit your specific needs, from prototype development to series production.
The preform design and configuration are meticulously specified to ensure optimal performance. This includes the customization of the core profile, which can be either step-index or graded-index, and the selection of dopant options such as Germanium, Fluorine, Boron, or Rare-earth elements. These elements are crucial in achieving the desired numerical aperture. Additionally, LEONI provides precise geometry for the preform, determining the shape of the core and cladding to meet application-specific assembly requirements.
LEONI employs advanced process technologies to produce each preform with precision. The production process begins with selecting the appropriate core material, which may involve using undoped fused silica with varying OH content or directly coating doped fused silica. The final waveguide preform is produced using LEONI's proprietary MCVD process for graded-index and step-index fibers or the PBVD process for large core step-index fibers. Each preform undergoes rigorous quality monitoring to ensure it meets strict performance criteria, resulting in preforms that deliver exceptional performance during fiber drawing for demanding applications.
LEONI offers graded index preforms specifically designed for high-performance multimode fibers, available in 50/125 and 62.5/125 configurations. The innovative MCVD production technique guarantees that the specified fiber performance properties are consistently met. On request, this graded index preforms can be delivered with a handle, facilitating their use in drawing towers. This attention to detail ensures that LEONI's preforms not only meet but exceed industry standards, providing reliable and efficient solutions for a wide range of fiber optic applications.

Frequently Asked Questions
Each preform is produced with the suited technology: Step 1 - choice of the appropriate core material, either from their raw material production of undoped fused silica with high or low OH content or by direct coating of doped fused silica. Step 2 - Production of the final waveguide preform, either their own MCVD process (inner coating) for graded-index and step-index fibers or a PBVD process (outer coating) for large core step-index fibers.
The performance properties of the 50/125 and 62.5/125 preforms include core composition of SiO2/GeO2, refractive index profile nearly parabolic, refractive index delta of 13.7 × 10–3 and 25.9 × 10–3 respectively, tolerance of Delta within a rod of 2.0 × 10–3 and 3.0 × 10–3 respectively, and numerical aperture of 0.200 ±0.015 and 0.275 ±0.015 respectively.
FiberTech Multimode Preforms are high-quality preforms made of highly pure fused silica materials that are used as the basis for the manufacturing and application of high-performance special fibers and standard fibers.
The acceptable number of bubbles per preform in the core is not allowed for s > 2.0, 0 for s ≤ 0.3, 5 for 0.3 < s ≤ 0.8, and 2 for 0.8 < s ≤ 2.0. There should be no bubbles in the cladding.
LEONI offers graded-index preforms for high-performance multimode fibers in the 50/125 and 62.5/125 designs.
