The QP- EDFA -B erbium-doped fiber power amplifier (EDFA) uses high-performance pump laser, high gain erbium-doped fiber, and unique control and protection circuit to achieve low noise and high stability output. The front panel provides power switch, LCD power display, and output power mediation knob, while providing RS232 interface, usually being used as a power fiber amplifier in optical fiber sensing and fiber optical fiber communication systems.
Features:
- Saturation output optical power 23dBm
- Low noise figure
- Input / output optical power display
- Output power adjustable
- Automatic shut off pump protection
- Remote control
- Desktop and module are optional
Applications:
- Optical fiber sensing system
- Optical fiber communication
