FiberTech Singlemode Germanium-Doped Step-Index Preforms
Description
The j-fiber group offers preforms with Germanium-doped core for the manufacturing of special step-index fibers. In order to ensure the specified fiber transmission properties, the preforms are produced using j-fiber's own MCVD technique. The highly photosensitive singlemode preforms were developed for the efficient production of fibers for FBG inscribing.

Frequently Asked Questions
Each preform is produced with the suited technology: Step 1 involves the 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 involves the 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 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. Bubbles are not allowed in the cladding.
FiberTech Singlemode Germanium-Doped Step-Index Preforms are preforms with Germanium-doped core for the manufacturing of special step-index fibers.
The MCVD technique is used to ensure the specified fiber transmission properties in the production of preforms.
The dopant options available for preforms are Germanium, Fluorine, Boron, or Rare-earth elements.
