LOW LOSS OPTICAL FIBERS WITH FLUORINE AND CHLORINE CODOPED CORE REGIONS |
| 摘要 |
A co-doped optical fiber is provided having an attenuation of less than about 0.17 dB/km at a wavelength of 1550 nm. The fiber includes a core region in the fiber having a graded refractive index profile with an alpha of greater than 5. The fiber also includes a first cladding region in the fiber that surrounds the core region. Further, the core region has an effective refractive index of about −0.10% to about +0.05% compared to pure silica. In addition, the core region includes silica that is co-doped with chlorine at about 1.2% or greater by weight and fluorine between about 0.1% and about 1% by weight. |

1. A single mode optical fiber, comprising:
a fiber having an attenuation of less than about 0.17 dB/km at a wavelength of 1550 nm, the fiber comprising a core region in the fiber having a graded refractive index profile with an alpha of greater than 5; and a first cladding region in the fiber that surrounds the core region, wherein the core region has an effective refractive index of about −0.10% to about +0.05% compared to pure silica, and further wherein the core region comprises silica co-doped with chlorine at about 1.2% or greater by weight and fluorine between about 0.1% and about 1% by weight. |
