Photonetics FIBERAMP-BT 17 EDFA – Erbium-Doped Fiber Amplifier

The Photonetics FIBERAMP-BT 17 is an Erbium-Doped Fiber Amplifier (EDFA) engineered for optical signal amplification across C-band wavelengths in telecommunications, data centers, and research environments. It delivers saturated output power of +17 dBm with typical small-signal gain exceeding 35 dB at 1530 nm, maintaining a low noise figure of 4.5 dB across variable signal and pump power levels.

– Compatibility & Integration

The FIBERAMP-BT 17 addresses gain variation challenges inherent to conventional EDFAs by maintaining flat spectral response and controlled dynamic range. WDM applications benefit from predictable gain across the C-band, though equalization schemes may require wavelength-specific optimization for networks with restricted dynamic ranges or multiple add-drop points.
