Erbium-doped fiber amplifier (EDFA)
Neptec’s Erbium-doped fiber amplifier (EDFA) modules are designed for optical network signal amplification and long term reliability. Neptec’s EFDA and Polarization Maintaining (PM) EFDA modules offer >30dBM output power with minimal noise and power consumption. APC (automatic power control), AGC (automatic gain control) and ACC (automatic current control) systems are designed into the amplifier to ensure successful system integration and stability.
Every network is different. Neptec ensures that every product we sell is highly customizable to fit any optical fiber application. If the standard EDFA below do not fit your application, we would be glad to review your specifications and quote a custom EDFA for you.
