Abstract
The invention relates to the transmission of optical signals (C-B,L-B) in conventional transmission bands, especially C-bands and L-bands, and of additional optical signals (S-B) in the S-band by means of an optical fiber (OF). At least one optical pump signal (ps, ps) is coupled into the optical fiber (OF) for amplifying the additional optical signals (S-B) 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 (ps, ps) is situated in the wave range of 1,320 nm to 1,370 nm.
