ABSTRACT:
Optical waveguide fiber that is bend resistant and single mode at 1260 nm and at higher wavelengths. The optical fiber includes a core of radius R1and cladding, the cladding having an annular inner region of radius R2, an annular ring region, and an annular outer region. The annular ring region starts at R2, and the ratio R1/R2is greater than 0.40.
