| 20080304138 | Optical Amplifier Comprising a Pump Module - In one aspect, an optical amplifier including a pump module, preferably for amplifying channels of a WDM-signal is provided. The outlet thereof is connected to an amplifying fibre wherein signal radiation formed by optical signals is amplified. In order to amplify the optical signals with minimum gain spectrum difference, i.e. in the WDM-technique with minimal channel level differences, pump radiation emerging from the pump module has a mode field diameter in the amplification fibre which is selected so that it is smaller than a mode field diameter of the signal radiation. | 12-11-2008 |
