Frequently Asked Questions

Each preform is produced with the suited technology: Step 1 ➔ choice of the appropriate core material, either from our 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 our 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 Singlemode Photosensitive Germanium-Doped Step-Index Preforms are preforms with Germanium-doped core for the manufacturing of special step-index fibers.

The typical values for the wavelength, radius, and refractive index of the preforms depend on the type of preform, such as TYPE 62.5/125/245 or TYPE 50/125/245.

The MCVD technique is used to ensure the specified fiber transmission properties during the production of these preforms.

The dopant options available for these preforms are Germanium, Fluorine, Boron, or Rare-earth elements.
