EDFA 1550nm amplifier
Product overview
This series is a most practical adjustable power amplifier, this machine adopt international famous brand of the pump laser and the United States OFS erbium doped fiber, has low noise, saturated output power, improve the reliability of the APC, ACC, ATC control and good ventilation and heat dissipation design, to ensure the pump laser and the whole life a stable job, through the front panel buttons to adjust the output optical power, regulating range every 0.1dBm, 3.0dBm down. The input optical signal is lost, the laser automatic closing, the pump laser itself play a good role in the protection, applicable to the central office, branch and line relay, can also be used for other optical fiber communication network, CATV system is the most commonly used, the most dosage is a fiber amplifier. This machine is equipped with a microprocessor software, has a laser monitoring, digital display, fault alarm, network management and other functions, once the machine working parameters deviate from the software set the permission scope, the flashing red lights, warning.
Product features
1. Pump laser and erbium-doped fiber are imported.
2. The front panel is provided with input and output indicating lamp, an alarm lamp.
3. With RS-232 and RS-485 standard interface and advanced SNMP network management function.
4. Reliable optical power output stabilizing circuit and laser heating refrigeration stability control circuit.
5. Double backup switch power supply, can be used in the 110 - 254V or - 48V electric work.
