Abstract : Er-doped fiber amplifiers(EDFAs) are very attractive for applications to the near-future optical communication systems. High output power of +20 dBm was already reported by using 1.48 um pump LD modules2. Increasing the signal output power from EDFA will be one of the important issues for such uses as the booster amplifiers in long-haul transmission systems and in optical distribution network systems. In this paper, we report on development of an EDFA with signal output power more than +22 dBm by using high power 1.48 um pump LDs and integrating passive optical components. In addition, the components of the EDFA including an Er-doped fiber bobbin are installed in a small package to put it into practical use.
