| 摘要 |
The invention relates to the transmission of optical signals (C-Bein,L-Bein) in conventional transmission bands, especially C-bands and L-bands, and of additional optical signals (S+-Bein) in the S+-band by means of an optical fibre (OF). At least one optical pump signal (ps1, ps2) is coupled into the optical fibre (OF) for amplifying the additional optical signals (S+-Bein) by means of the Raman effect, whereby said additional signals are transmitted in the S+-band. The wavelength of the at least one optical pump signal (ps1, ps2) is situated in the wave range of 1,320 nm to 1,370 nm.
