LC Mechanical Variable Attenuator, MVOA Attenuator 0-30dB LC/PC VOA
Attenuator
LC 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.
