Product description
                                              In - Line Variable Optical Fiber Attenuator Optical attenuator
    Variable in-line optical attenuators comprises a dual fiber collimator and a reflection component separated by a linear moveable ND filter. They are used to permit dynamic control of optical power levels in a fiber and can be applied to adjust power level of signal in the optical communication at the output of light sources, E/O converters and for the linear or dynamic range of power meter.
     
    
    
    
    
     
    Features:
