Ytterbium-Erbium-doped fiber amplifier (YEDFA)
Compared to conventional amplifiers, Neptec’s Ytterbium-Erbium-doped fiber amplifiers (YEDFAs) are more compact, stable, and reliable while providing higher output power. YEDFAs utilize dual-stage amplification to maintain system increase amplification power without sacrificing stability. 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 operation.
Every network is different. Neptec ensures that every product we sell is highly customizable to fit any optical fiber application. If the standard YEDFA below do not fit your application, we would be glad to review your specifications and quote a custom YEDFA for you.
