The Keopsys KPS-BT2-C-18-WDM-LN-SD-FA is a C-band fiber optic amplifier engineered for optical communication systems and precision measurement applications demanding high signal integrity. This benchtop module integrates WDM technology with a low-noise design to deliver consistent performance across demanding operational profiles. The unit accepts input signals from −15 dBm to 0 dBm and produces 18 dBm saturated output power with greater than 20 dB small signal gain. Noise figure remains below 5 dB, while gain variation stays under 1.5 dB across the operating range. Polarization-dependent gain is suppressed to less than 0.5 dB, and polarization mode dispersion is below 1 ps. Automatic power control and automatic current control optimize performance without manual adjustment. FC/APC optical connectors and GPIB control interface enable straightforward system integration.
