SC Variable Fiber Optic Attenuators
SC Mechanical Variable Attenuator, MVOA Attenuator 0-30dB SC/PC VOA Attenuator
SC Mechanical variable optical attenuator is generally used in optical measurement. In the when
measure optical receiver sensitivity, usually place in the optical receiver input to adjust receiving
light power. It is in the middle of fiber connector, suitable for all kinds of fibre optic connector with
all high performance of connectors.
When use optical attenuator, please keep the environment clean and dry, put on the dust cap
when not in use, handle with care, strictly forbid collision.
Main usage:
(1) to control the power level: the output power of the vibration control in microwave super heterodyne
receiver, to get the best noise coefficient and frequency conversion loss, then get the best reception.
In the microwave receiver, automatic gain control, improve dynamic range.
(2) decoupling components: as to the coupling element between the oscillator and the load.
(3) the relative standard: as a comparison of the relative standard of power level.
(4) jump attenuator in radar anti jamming: it is a variable attenuator whose attenuation value
can mutate,usually without introducing attenuation, encountered outside interference, a sudden increase in attenuation.
