A 90-nm wideband (1500-1590nm) optical amplifier consisting of a dispersion-compensated-fiber-based Raman fiber amplifier and a semiconductor optical amplifier with gain clamping and dispersion compensation is demonstrated for wide bandwidth amplification with gain flatness as well as dispersion compensation. 10Gb/s DWDM transmission over 100-km conventional single-mode fiber link with low biterror-
rate power penalty of 0.4 dB is achieved for such gain-clamped amplifier with a lasing light at 1508 nm, which suppresses the cross-gain modulation effect of the used SOA. This amplifier will play an important role in metropolitan area network (MAN) for high speed and broadband delivery between city interconnection.
