A flexible sealing assembly () for an optical fiber draw furnace () comprising a first plurality of curved ring sections () arranged in a circular arrangement and a plurality of tension loaders () exerting continuous radially inward force on at least one curved ring section. Each curved ring section of the first plurality of curved ring sections () is separated from each other and defined by the same radius of curvature. Further, the first plurality of curved ring sections () is radially movable such that the first plurality of curved ring sections () creates a seal between a glass preform () and a vertical hollow body () in the optical fiber draw furnace (). The diameter of the glass preform () varies.

Flexible sealing assembly for optical fiber draw furnace and optical fiber

The present invention relates to an optical fiber with improved bend performance and manufacturing method thereof. The optical fiber () comprises a core region () defined by a core refractive index profile () and a cladding region () surrounding the core region defined by a cladding refractive index profile (). Particularly, the core region has a first core () defined by a first core refractive index (RI) profile () and a first core RI max (Δpeak) and a second core () defined by a second core RI profile () and a second core RI max (Δcore). Moreover, the cladding region further comprises a first cladding () and a third cladding () composed of pure silica and a second cladding () composed of a down-doped silica, where the down-dopant is fluorine.
