CEFA-C-HG SERIES

CW ERBIUM FIBER AMPLIFIER C-BAND HIGH GAIN

1.5µm
• High sensitivity with very low input power
(- 50dBm)
• High small signal gain up to 50dB
• Near quantum-limited noise figure
• Polarization-maintaining available
• Choice of turnkey benchtop or module

Description
The CEFA-C-HG series Erbium doped fiber
amplifiers are designed to amplify very weak
optical signals.
Amplified spontaneous emission is limited in profit
to the output signal-to-noise ratio. A near quantum
limited noise figure and a small-signal gain greater
than 50 dB are achieved at low input power (-50
dBm).
Polarization-maintaining models are available with
very good polarization extinction ratio.
These amplifiers are proposed in turnkey benchtop
instruments or in modules.
