Inquiry

Manual variable optical attenuator (Manual VOA) can be used for power control and equalization for WDMs, FTTx, CATV and Test & Measurement instruments. it is a device designed to attenuate an intensity or power level of an input optical beam in a controlled manner to produce an output optical beam with different attenuated intensities. .

Mechanical Variable Micro-Optics type attenuator uses a mechanical method to produce attenuation. Typically light is coupled out of the fiber using a collimator lens and a precision screw mechanism blocks a portion of the light before it is coupled back in to the fiber.

Mechanical variable Air Gap type attenuator utilizes an air gap between the ends of two fibers to attenuate the transmission signal. Attenuation can be adjusted by means of self-locking screw mechanism.

We provide stable performance over wide temperature and wavelength ranges manual variable optical attenuator. They have low insertion loss and high resolution/repeatability. In addition, its compact design is excellent for mounting on panel. Specific type of fiber connector can be built on each end. 

Besides Manual Variable Optical Attenuator, we also offer other Variable type optical attenuator (Variable Plug-in optical attenuator, Variable Adapter Type optical Attenuator, Variable In-line optical Attenuator) and fixed type optical attenuator (Fixed Plug optical Attenuator, Fixed Adapter type optical AttenuatorFixed In-line optical Attenuator, Fixed Hybrid Adapter optical Attenuator) for your different application.
