Abstract
The present disclosure provides an optical fiber (10) comprising one or more glass cores (12, 12<sub>1</sub>, 12<sub>2</sub>, 12<sub>3</sub>, 12<sub>4</sub>) extending along a length of the optical fiber (10) and a glass cladding (14) with a peripheral region (16), one or more interface regions (18, 18<sub>1</sub>, 18<sub>2</sub>, 18<sub>3</sub>, 18<sub>4</sub>) and one or more intermediate regions (20, 20<sub>1</sub>, 20<sub>2</sub>, 20<sub>3</sub>, 20<sub>4</sub>). The optical fiber (10) comprises an alumina (Al<sub>2</sub>O<sub>3</sub>) doping in the entire glass cladding (14) or at least one of the peripheral region (16), the one or more interface regions (18, 18<sub>1</sub>, 18<sub>2</sub>, 18<sub>3</sub>, 18<sub>4</sub>) and the one or more intermediate regions (20, 20<sub>1</sub>, 20<sub>2</sub>, 20<sub>3</sub>, 20<sub>4</sub>), provided that, when the optical fiber (10) comprises a single glass core (12), the alumina doping in the intermediate regions (20, 20<sub>1</sub>, 20<sub>2</sub>, 20<sub>3</sub>, 20<sub>4</sub>) is distributed among multiple intermediate regions (20, 20<sub>1</sub>, 20<sub>2</sub>, 20<sub>3</sub>, 20<sub>4</sub>) or included in combination with alumina doping in at least one of the peripheral region (16) and the one or more interface regions (18, 18<sub>1</sub>, 18<sub>2</sub>, 18<sub>3</sub>, 18<sub>4</sub>).
