  • Variable attenuator optical power meter

    Variable attenuator optical power meter

    This hand-held Fiber Optic Variable Attenuator & Optical Power Meter is a precision handheld instrument commonly used for testing single mode fiber systems for optical system margin and linearity. It is equipped with two additional, independent optical power meters and based on electrically controlled variable optical attenuator (VOA) modules. Attenuators are essential building blocks when developing test stations for applications such as bit-error-rate (BER) testing of transmission cards or gain and noise characterization of erbium-doped fiber amplifiers (EDFAs). Attenuators emulate signal loss, balance power levels, and protect sensitive devices during testing. This allows output power, for example, to be stabilized at one value even when input power is unstable.
