Abstract

An erbium-doped fiber amplifier (EDFA) gain-clamped to a flat gain spectral region was designed and built up. The dynamic gain equalized transmission over an 8 × 2．5Gb/s ×450 km WDM system with a G．652 fiber was demonstrated by using cascaded gainclamped EDFAs. When the channel number changed, the sensibility of the receiver varied　only 0．5 dB at BER of 10-12.
