Network Management EDFA In Optical Fiber , Custom Erbium Fiber 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 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.
Features
◆ YGF1522T-C optical amplifier adopts the world famous companies mature 1550nm modular technology. The core components are imported components, which guarantee the high quality and high reliability of the products;
◆ Built-in perfect and reliable optical power output stabilization circuit and laser thermoelectric induced temperature stability control circuit to ensure the best performance of the whole machine and long life of the laser;
◆ Built-in MCU microprocessor, the microprocessor software monitors the working state of the pump laser, and the working parameters are displayed by the panel (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 power, and the red light flashes to alert the alarm, and the panel display indicates the cause of the fault;
◆ Plug-in RJ45 Internet port responder, support SNMP network management protocol, Telnet, support the SFTH integrated network management system;
◆ It adopts 19'' 1U standard rack, built-in high-performance main and standby switching power supply, can work in the city voltage of 165～260V, and supports hot plugging.
◆ Built-in WDM or FWDM wavelength division multiplexer to achieve full-band multi-service transmission from 1535 to 1565nm.
