Title:
光増幅用ファイバ、光ファイバ増幅器及び光通信システム
Document Type and Number:
Japanese Patent JP4494850
Kind Code:
B2
Abstract:
An optical amplification fiber for an optical fiber amplifier that amplifies a signal light using a pumping light has an absorption coefficient that satisfies conditional relations alphas>=2.0 dB/m and alphap/alphas>=-0.0697xalphas+1.30, where alphap is the absorption coefficient in a pumping light wavelength band, and alphas is the absorption coefficient in a signal light wavelength band.
