High-Gain Erbium-doped Fiber Amplifier (LNA-220)

  • LNA-220

    The LNA-220 is a specially designed Erbium-doped fiber amplifier which 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 3.8dB, and a small-signal optical gain of over 50dB is achievable with input signal as low as -50 dBm reflecting the impact of the specialty fiber and composite amplifier design, making it an indispensable amplifier for weak optical signals.
