Multi-wavelengths Low Noise Erbium-doped Fiber Amplifier (WLN-220)
- High optical signal gain >40 dB
- Ultra low noise amplification
- Near quantum-limited noise figure
- Multi-wavelengths amplification
- Gain flattening
The WLN-220 is a specially designed Low Noise Erbium-doped fiber amplifier for DWDM application with gain flattening feature. It offers a superior optical amplication performance with a very high gain factor and a minimal added noise. A near quantum limited noise figure of typically 4.0dB, and a small-signal optical gain of over 40dB is achievable with input signal as low as -35 dBm reflecting the impact of the specialty fiber and composite amplifier design, making it an indispensable amplifier for weak optical signals.
- Weak optical signal extraction
- Space or satelite communication
- Test and measurement
- LIDAR detection amplifier
- Quantum encryption applications
