## Abstract A novel Lโband fiber amplifier comprised of two sections of erbiumโdoped fiber (EDF) and an optical reflector is used to enhance powerโconversion efficiency (PCE). We also examine how an optical amplifier can be used without an optical reflector while nonetheless making effective use of
## Abstract Gain clamping in a longโwavelengthโband erbiumโdoped fiber amplifier (Lโband EDFA) using a C/Lโband WDM coupler is demonstrated. The gain for the amplifier is clamped at 15.5 dB with a gain variation of less than 0.2 dB from input signal power ranging from โ40 to โ14 dBm with almost neg
