AMS Technologies product portfolio includes a range of selected optical amplifiers for many standard telecom and datacom tasks. All three of the common amplifier formats are available – erbium-doped fiber amplifiers (EFDAs), ytterbium-doped fiber amplfiers (YDFAs) and semiconductor optical ampfliers (SOAs).
"Amplifying repeater links are a vital aspect in mantaining high performance and in providing a route to low cost in optical communication networks. Through adequate reamplification at multiple stages along a transmission path, an optical signal can maintain signal integrity over a much greater distance between points at which the optical signal is finally converted into an electronic signal.
For operation in both the C and L communication bands, AMS Technologies provides a selection of cw and pulsed erbium-doped fiber amplifiers (EDFAs) in a wide range of configurations and gains."
