Scalable EDFAs simplify metro design

Author: J.J. Pan, Joy Jiang, Xiangdong Qiu, Kejian Guan

Publication: Printed in WDM Solution magazine, July 2002, pp.15-19

Abstract: Elimination of gain-flattening filters and pump-laser coolers makes the narrowband EDFA practical as an amplification solution for metro applications. With fewer components than the wideband EDFA, the narrowband EDFA offers a more compact, cost-effective design.
