| 摘要 |
An optical amplifier and optical amplifier arrangement with reduced cross phase modulation wherein in an active fiber of the optical amplifier, the fiber being doped with ions of elements from the group of rare earths, in order to reduce the cross phase modulation of the optical amplifier, at least one active fiber section is allocated a dispersion coefficient having a high magnitude, in which the optical transmission signal to be amplified assumes a high signal level.
