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 easy to form a population inversion between the metastable state and the ground state. At the same time, the signal photons pass through the erbium-doped fiber. Under the effect of the stimulated radiation, a large number of photons are completely identical to themselves, so that the signal photons are rapidly increased, so that the optical signal that is continuously amplified can be obtained at the output end.

Huanshun YGF15XXT series Optical Amplifiers adopt mature 1550nm Modular Technology, core components apply JDSU, BOOKHAM, FITEL Imported Original Pump laser, brand new optical passive components, with optoisolator high linearity, low noise distribution feedback Pump Laser, combined with microprocessor technology and ATC and APC automatic control technology, the technical indexes of excellent performance are guaranteed. The Optical Amplifier Modular has features of Small Noise Factor, High Input and Output Isolation, Small Nonlinear Distortion and so on. The built-in microprocessor monitors all operating parameters of the pump laser and the operating parameters are displayed on the LCD. Once the operating parameters of the laser deviate from the allowable range of the Set Value, the Microprocessor will automatically turn off the Laser and the Red Light flashes Prompt Alarm, the panel display Prompts the Cause of Failure. This device use the Pluggable Transponder, support WEB and SNMP, can realize the Network Management and Remote Monitoring.
