An optical attenuator, or fiber optic attenuator, is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable. The power reduction is done by such means as absorption, reflection, diffusion, scattering, deflection, diffraction, and dispersion, etc.

Touch the red probe (positive) to the suspected anode and the black probe (negative) to the cathode. If reversed, the reading will show "OL" (open loop), indicating reverse bias. As a bipolar component, a diode has an anode and a cathode at its two terminals, just like the positive and negative terminals in a circuit power source. How to Determine If a Diode is Forward or Reverse Biased? Can You Test Polarity with a Multimeter? What is Diode Polarity? Diode polarity refers to the direction in which a diode allows electrical current to flow. If it produces light, you were right, if it produces smoke, you were wrong :) Im 50% sure the left is negative.
