19′′ 1U Standard Rack EDFA Optical Amplifier With MCU Microprocessor

19′′ 1U Standard Rack EDFA Optical Amplifier With MCU Microprocessor EDFA Optical Amplifier Summary: The 1550nm erbium-doped fiber amplifier uses the erbium-doped fiber as the active medium. When the pump optical is input into the EDFA, most of the ground-state Er3+ can be pumped to the excited state. The excited state of Er3+ is quickly and non-radiative. The transfer to the metastable state, due to the average residence time of Er3+ on the metastable state is 10ms, it is
