Insertion Loss Calculator

Your details

Power mode uses Pin/Pout; voltage mode uses Vin/Vout; fiber mode totals cable attenuation, connectors and splices.

  • Moderate insertion loss - check for impedance mismatches, degraded connectors, or excessive cable length.
  • 50.0% of the input power reaches the output; 50.0% is lost in the path.

Next stepTo reduce insertion loss, check connector cleanliness, use lower-loss cable, and ensure impedances are matched throughout the path.
