Gain clamping in a long-wavelength-band erbium-doped fiber amplifier (L-band EDFA) using a C/L-band 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 -40 to -14 dBm with almost negligible noise...
