Description of Variable Attenuator

The Variable Attenuators are waveguide components for tunable signal leveling or reflection compensation in waveguide networks. Optical variable attenuator is a double window (1310/1550nm) of passive components. The variable optical attenuator could continually and variably attenuate the light intensity in the optical fiber transmission. Variable fiber optic attenuator could help simulate distance or actual attenuation in the fiber optic testing work by inserting a calibrated attenuation into the link.


Variable fiber attenuator can help user vary the light power injected from a light source into the optical fiber. Important parameter of variable fiber attenuator includes its insertion loss, reflection loss and attenuation range. SOPTO supply ST, FC, SC, LC variable fiber optic attenuators with APC, UPC type. Attenuation range available is from 1dB to 30dB.


Applications of Variable Attenuator

  1. Fiber sensors

  2. CATV

  3. Test equipment

  4. Fiber-to-the-home

  5. Telecommunications
