Abstract
An optical fiber with large effective area, low bending loss and low attenuation. The optical fiber includes a core, an inner cladding region, and an outer cladding region. The core region includes a spatially uniform updopant to minimize low Rayleigh scattering and a relative refractive index and radius configured to provide large effective area. The inner cladding region features a large trench volume to minimize bending loss. The core may be doped with Cl and the inner cladding region may be doped with F.
Claims21
A method of making an optical fiber comprising:
- forming soot from an organosilicon compound;
- and
- doping said soot with Cl, and
- sintering said doped soot, said sintered doped soot having a Cl concentration of at least 0.8 wt %.
