摘要：
The authors report the first use of a praseodymium-doped fluoride fibre amplifier (PDFFA) in a 24 TV channel FM-SCM transmission experiment. 24 analogue FM-SCM-TV channels were amplified by a PDFFA without any observable degradation in picture quality. By using a single PDFFA as a post-amplifier, transmission over 100km of 'standard' 1:3 mu m optimised fibre was demonstrated with a total loss budget of 45dB. By using the same PDFFA as an inline amplifier, a loss budge of 53dB was achieved.
