Abstract
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.
