摘要： The invention concerns a wavelength converter for converting a first light signal used for data-transmission and having a first wavelength ( lambda In) into a second light signal having a second wavelength ( lambda Out). The wavelength converter signal comprises a signal input for picking up the first light signal, a signal output for emitting the second light signal, a modulatable optical semiconductor amplifier (4) with an input, an output and modulation input and a first laser light source (L1), which forms a first stage (1) with the semiconductor amplifier (4). The input of the semiconductor amplifier (4) is connected to the first laser light source (L1) and the modulation input of the semiconductor amplifier (4) is connected to the signal input for cross-amplification modulation. The first laser light source (L1) emits light with a third wavelength ( lambda int). Arranged downstream of the first stage (1) by means of an optical coupler (3) is a second stage (2) which contains a modulatable second laser light source which emits light at the second wavelength ( lambda Out) and has a modulation input and an output. The modulation input of the second laser light source is connected to the output of the semiconductor amplifier and the output of the second laser light source is connected to the signal output.
