Single-mode/Polarization Maintaining Single-mode Fiber Attenuation Range: IL-60 dB
Low Insertion Loss, High Return Loss
Digital Control with LCD Display
The digital adjustable fiber optic attenuator offered by LBTEK features a blocking type (single-mode/polarization maintaining single-mode fiber) or variable neutral density filter type (multi-mode fiber) attenuation mechanism. It uses a microcontroller to control the speed and precision of the internal stepper motor to adjust the attenuation level. LBTEK's digital adjustable attenuator is a handheld device equipped with an LCD display and an easy-to-use user interface. Users can directly input wavelength and attenuation values via the keypad or use the built-in USB interface for computer-based attenuation control. The product includes a USB connection cable and power adapter, but does not include fiber optic cables. It is recommended to use the digital adjustable attenuator at the calibration wavelength, with an operating wavelength range of 350-2050 nm. For further details, please consult LBTEK technical support.
