Chapter 1Module IntroductionConstant Power Flat Mode (Optional)Variable Gain-Flattened <strong>EDFA</strong>s can optionally be operated in Constant Power Flatmode. By default, the output power is the nominal output power for the gainflattened<strong>EDFA</strong>, which is equal to the composite output power at fully loadedcondition in the Constant Gain mode. The output power can be set to other valuesbetween 5 dBm and the nominal output power in 0.5 dB steps, as shown in thefollowing table.Model Composite Output Power (POUT/C) NoteP2-HD-<strong>EDFA</strong>-VGF-17-SA 5 dBm – 17 dBm, 0.5 dB stepP2-HD-<strong>EDFA</strong>-VGF-20-SA 5 dBm – 20 dBm, 0.5 dB stepP2-HD-<strong>EDFA</strong>-VGF-21-SA 5 dBm – 21 dBm, 0.5 dB stepPIN/C >0 dBmPIN/C >0 dBmPIN/C >0 dBmThis mode of operation maintains gain flatness as long as the gain is within thespecified range for the model.18 78-4037880-01 Rev B
