Erbium Doped Fiber Amplifier (EDFA)

All-optical gain-clamped erbium doped fiber amplifier with high gain, low noise figure and excellent output power stability. Conventional EDFAs try to obtain a constant gain for varying input signal powers using an electronic feedback mechanism. An electronic feedback mechanism needs a relatively long time to regulate amplifier gain. Our EDFAs are built on a new kind of all-optical gain-clamping technology. Using this new technology, a stable gain-clamped amplifier operation is provided for a wide dynamic range of signal input power in real time. Our new products include C, L and C+L Band gain-clamped erbium doped fiber amplifier types which are precisely designed and manufactured to be efficiently used in wideband DWDM and Ultra DWDM fiber optical communication systems and optical distribution networks.
