Multi-wavelengths Low Noise Erbium-doped Fiber Amplifier (WLN-220)

  • WLN-220

    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.
