摘要： The present disclosure relates to an optical fiber (100) with a core (102) extending along a central axis (112), a cladding (104) surrounding the core. The core comprises a first up-dopant and a second up-dopant. And, the cladding comprises a first cladding (106) surrounding the core, a second cladding (108) surrounding the first cladding, and a third cladding (110) surrounding the second cladding. The first cladding has a second up-dopant, the second cladding has down-dopant, and the third cladding is undoped. Further, the first cladding (106) has traces of the first up-dopant and the down-dopant, the second cladding (108) has traces of the second up-dopant, and the third cladding (110) has traces of the down-dopant.
