QP-EDFA -P model The erbium-doped fiber amplifier (EDFA) uses high-performance pump laser, low noise 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 front fiber amplifier for fiber optic sensing and fiber optic communication systems.
Features:
- Minimum input optical power -45dBm
- Low noise index
- Input / output optical power display
- Output power adjustable
- Automatic shut off pump protection
- Remote control
- Desktop, module package are optional
Applications:
- Optical fiber sensing system
- Optical fiber communication
