Variable In-line Fiber Optical Attenuator VOA ST SM UPC APC 0-60dB
SZOPT offers a complete line of variable
in-line optical attenuators.These variable optical attenuators allow the user
to manually vary the attenuation of the signal in the fiber as it is
transmitted through the device. These variable attenuators can be used to
precisely balance the signal strength in a fiber optic circuit or to balance
the optical signal when evaluating the dynamic range of the measurement system.Please
reach us for details.
