This paper reviews recently developed ultra-broadband EDFAs which include an amplifier composed of a 1.55 μm-band and a 1.58 μm-band gain-flattened EDFA in a parallel configuration and an Er3+-doped tellurite fiber amplifier. Furthermore, it dcscribes improvements in the 1.55 μm-band gain-flattened fluoride-based EDFA.
