FAQ

What is the Insertion Loss?
Insertion loss is the loss of signal power resulting from the insertion of a device in a transmission line or optical fiber and is usually expressed in decibels (dB). Insertion Loss is usually measured using the Decibel for Noise. Note that the value of Insertion Loss is always positive.
Can the Insertion Loss be negative?
No, the Insertion Loss, measured in Noise cannot be negative.
What unit is used to measure Insertion Loss?
Insertion Loss is usually measured using the Decibel[dB] for Noise. Neper[dB], MilliDecibel[dB] are the few other units in which Insertion Loss can be measured.
