Recently, most of the difficult problems which prevented the realization of soliton communication have been solved by using the so-called erbium-doped optical fiber amplifiers (EDFAs). These amplifiers can provide a larger gain with a lower pumping power than the Raman process. In this paper, we describe how we were able to realize an actual soliton transmission system which utilizes lumped amplifiers instead of distributed amplifiers. A data transmission experiment at 10 Gbit/s 300 km is presented.
