Ultra
Low Noise Optical Amplifier <LNA-150>
- High Gain Erbium-doped Fiber
Amplifier -
|
LNA-150 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, reflects the impact of
the specialty fiber and amplifier design employed in the LNA-150.
It is an indispensable optical amplifer for applications to
detect weak optical signals. For signal channel application, an even
higher signal-to-noise performance can be realised when used together
with the Alnair WTF-200 or BVF-200 series narrow band optical filter to
further
suppress the out-of-band noise.
