ABSTRACT We have demonstrated multichannel wavelength-division multiplexed
optical signal transmission experiments employing Er-doped fiber
amplifiers. Four-channel transmission of 459 km and 1500 km experiments
and two-channel transmission of 4550 km experiment are described, and
the transmission penalty is analyzed. We also discuss the effect of
four-wave mixing. The difference of the transmission fiber clearly shows
the difference of the optical spectrum due to four-wave mixing after
long-distance transmission. The results show the possibility of
long-distance multidestination optical communication systems with
wavelength-division multiplexed signals combined with Er-doped fiber
amplifiers
