Abstract: The technology of this application relates to an erbium-doped fiber. The erbium-doped fiber can be used in the fields of amplifiers, optical communications, rare-earth-doped fiber preparation, and the like. A fiber core of the erbium-doped fiber includes a first layer and a second layer from inside to outside. The first layer includes a center of the fiber core. The second layer is an annulus, and an outer ring of the annulus is an outer ring of the fiber core. An average doping concentration of erbium ions of the first layer is higher than an average doping concentration of erbium ions of the second layer. An ASE can be reduced by reducing a doping concentration of erbium ions of the second layer, to further reduce a noise figure of the erbium-doped fiber and improve communications quality.
