Abstract :
Summary form only given. In-line amplifier transmission using erbium-doped fiber amplifiers (EFDAs) has been realized in 5-Gbit/s transoceanic systems in 1995-1996. In Japan, a 900-km in-line amplifier system with a data rate of 2.5 Gbit/s, upgradable to 10 Gbit/s, started service in May 1995. All of these systems use nonreturn-to-zero (NRZ) signal formats. Solitons are another candidate for long-distance transmission. This paper compares the choices for the next step in large-capacity long-distance systems.
