Variable Fiber Optic Attenuator Specifications   (58KB)

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. By using the variable fiber optic attenuator, technicians could verify the power margin received by testing the fiber optic link power budget. 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 include its insertion loss, reflection loss and attenuation range.

This variable fiber attenuator works with typical 9/125 single mode fibers at 1310/1550nm. It is with FC fiber connector interface, insertion loss typical 2.5dB and return loss ≤-40dB,the variable fiber optic attenuator is with simultaneous LCD display of wavelength, input power, output power, current attenuation and selected attenuation step. Its attenuation step size is 0.05dB, 0.1dB, 0.5dB, 1dB and 5dB optional, attenuation range from 2.5dB to 25dB.
