Preforms

Pref-1-spalt

Based on the combination of two highly optimized and effective processes, PBVD and MCVD, as well as our new fused silica process, j-fiber and subsidiary j-plasma offer a large portfolio of standard and individually
customized preform designs for the manufacturing of standard and specialty optical fibersmore...

Tubes

Rohre

j-FST Fluorine Doped Silica Tubes feature highest fluorine concentrations thus being the perfect material for individual preform designs and innovative specialty fiber making. j-FST tubes are available as uniformely doped tubes or customized with double or multi step refraction index profiles. more...

Rods

SQ-Walze-mit-Mensch2

j-fiber offers doped and undoped silica rods under the brands j-plasil (undoped synthetic silica for operation in the VIS, NIR and IR range) and SQ (high-purity fused synthetic UV silica for fiber optics)more...
