| Zusammenfassung: | An optical fiber amplifier has two fiber optical parts connected to each other. The first optical fiber part is provided with a pumping light source (32) directed away from the second part, which doesn't have a pumping light source. A reuse means for using backward amplified spontaneous emission (ASE) from the first fiber as a secondary pumping light source applied to the second part. An independent claim is also included for a method for amplifying an optical signal. |
