An optical fire amplifier comprises a thulium-doped optical fibre (2) pumped at 790 nm by a semi-conductor diode laser (20) coupled to the fibre (2) via optical fibre coupler (12). The amplifier (2) is optically coupled in series to a pair of systems fibres (18 and 14) to provide amplification to optical signals.

L'invention est un amplificateur à fibre optique comportant une fibre optique dopée au thulium (2) pompé à 790 mm par un laser à diode (20) couplé à la fibre (2) par un coupleur de fibres optiques (12). L'amplificateur (2) est optiquement couplé en série à une paire de fibres (18 et 14) pour amplifier les signaux lumineux.
