Description
Using highly pure fused silica materials, the LEONI subsidiary j-fiber develops and produces high-quality preforms according to customer specifications. They are the basis for the manufacturing and application of high-performance special fibers and standard fibers. LEONI offers graded-index preforms for high-performance multimode fibers in the 50/125 and 62.5/125 designs.

Frequently Asked Questions
The performance properties of the 50/125 and 62.5/125 preforms include core composition (SiO2/GeO2), refractive index profile (nearly parabolic), refractive index delta (13.7 × 10–3 for 50/125 and 25.9 × 10–3 for 62.5/125), tolerance of delta within a rod (2.0 × 10–3 for 50/125 and 3.0 × 10–3 for 62.5/125), numerical aperture (0.200 ±0.015 for 50/125 and 0.275 ±0.015 for 62.5/125), and preform Ø (O.D.) (39.0 for 50/125 and 26.0 for 62.5/125).
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.
FiberTech Multimode Preforms are high-quality preforms made from highly pure fused silica materials that are developed and produced according to customer specifications. They are used as the basis for the manufacturing and application of high-performance special fibers and standard fibers.
Every preform is subject to strict quality monitoring that also includes the testing of the goal parameters. The result is a preform with best performance properties during the drawing of fibers for demanding applications.
LEONI offers graded-index preforms for high-performance multimode fibers in the 50/125 and 62.5/125 designs.
