Keopsys / Optocom Innovation KPS-BT-C-10-FA

The Keopsys/Optocom Innovation KPS-BT-C-10-FA is a C-band erbium-doped fiber amplifier engineered for optical communication and sensing applications requiring high output power and low noise performance. This microprocessor-controlled benchtop unit employs Keopsys’ proprietary VSP® (V-groove Side Pumping) technology to achieve efficient amplification across the C-band. Automatic Power Control (APC) and Automatic Current Control (ACC) maintain stable output regardless of input signal variations. An integrated GPIB interface enables remote operation, real-time diagnostics, and automated data acquisition, making the KPS-BT-C-10-FA ideal for both laboratory characterization and OEM system integration.
