Complete Your Setup
LBTEK's digital variable optical attenuators employ a blocking mechanism (for single-mode/polarization-maintaining single-mode fibers) or a variable neutral density filter mechanism (for multimode fibers), with attenuation levels adjusted via a microcontroller that precisely controls the speed and accuracy of the internal stepper motor. The LBTEK digital variable attenuator is a handheld device equipped with an LCD display and a user-friendly interface, allowing direct input of wavelength and attenuation levels via a keypad, as well as computer-based attenuation control through the built-in USB interface. The LBTEK digital variable optical attenuator comes with a USB cable and power adapter, but does not include optical fibers. It is recommended to use the digital variable attenuator at calibrated wavelengths, with an operational wavelength range of 350-2050 nm. For more details, please consult LBTEK technical support.
