Abstract :
The highest reported overall power conversion efficiency of 42% using a high Tm3+ concentration-doped fluoride fibre amplifier (TDFA) with one colour 1.4 μm pumping and a double pass configuration for S-band amplification has been achieved. This TDFA was used for a successful 8×10 Gbit/s WDM transmission
