What is the difference between insertion and return loss?

What is the insertion loss and return loss of a transformer?

  • For a given RF transformer, the Insertion Loss @ 10 MHz is 0.5 dB, and the Return Loss @ 10 MHz is 25 dB, with impedances of 50 Ohm. Let's say I put in a 1 V, 10 MHz sine wave, what happens? Return loss tells you how much of the input signal is reflected. Return loss is the ratio between the reflected power and input power:

What is the insertion loss and return loss of fiber connectors?

  • Different polishing styles of fiber connectors have varied core-to-core contact performance regarding the connector's insertion loss and return loss. Usually, the insertion loss of PC, UPC, and APC connectors is less than 0.3dB.

What is insertion loss in networking?

  • In telecommunications, insertion loss refers to the loss of signal power, calculated as a ratio in dB (decibel), resulting from inserting a device in a transmission line or optical fiber. It can also be referred to as attenuation, which indicates how much the signal loss is by comparing the input power to the output power.
