Single Wavelength
Erbium-doped
Fiber Amplifier(SW EDFA Module)
is a fiber amplifier product
series specially used in fiber laser or fiber communication system,
due to use semiconductor laser pumped
Erbium-doped
fiber
to provide gain to signal ,which has these
advantages of high energy conversion efficiency. high gain and low
noise. Our SW EDFA is easy to operate tests. The user can adjust the
pump current through the front panel, this changes the gain and
output power of the amplifier. We also provide compact EDFA module
for system integration, support PC software control and serial
command control.
It has two types: small signal
amplifier and booster amplifier
Small signal amplifiers
is PA,Pre-Amplifier, is dedicated to amplifying small optical
signals in the range of -45 dbm ~-25 dbm. the typical small signal
gain is as high as 35dB or 45dB and has a low noise coefficient.
usually used before an optical receiver to improve its sensitivity.
