## Abstract A novel reflection Lโband erbiumโdoped fiber amplifier, based on a fiber loop mirror, is constructed. This amplifier reflects the backward ASE to the EDF as a secondary pumping source. A gain of 30 dB (an increase of 6 dB) is obtained, compared to the forwardโendโpumped EDFA in the rang
## 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
