Abstract :
Repeaterless transmission systems are of great interest because of the increasing need for large capacity but economical transmission systems. Above all, remotely pumped amplifier systems are occupying peoples´ attention because they make it easy to increase the number of fibers per cable, are highly reliable, and do not increase construction time. This paper reviews remotely pumped amplifier systems and examines optical signal-to-noise ratio (SNR) designs. Theoretical and measured optical SNR are shown to agree well. Using these results, we predict the ultimate performance of remotely pumped amplifier systems. We show the feasibility of 400 km transmission at 10 Gbit/s and about 500 km transmission at 600 Mbit/s
