Abstract
An optical fiber is disclosed in which the core region of the optical fiber is doped with Cl and F in order to reduce the viscosity mismatch between the core region and the adjacent cladding region. In one embodiment of the invention, the optical fiber is a single-mode step index optical fiber having a core region doped with Cl and F in an amount effective to produce a difference in temperature between the glass transition temperature of the core region and the glass transition temperature of the adjacent cladding region of less than about 200° C.
