Fixed Gain-Controlled EDFA Modules

Single-stage, fixed gain-controlled EDFA modules have three LEDs on their faceplate:
• “P” to indicate the power supply status
• “Mod” to indicate the operation status of the module
• “1” to indicate the amplifier port status
Note
Please note, the module should lose power for at least 10 seconds to allow any and all
capacitance to dissipate.
