What is Insertion Loss?
Insertion loss is the amount of energy that a signal loses as it travels along a cable link. It is a natural phenomenon that occurs for any type of transmission—whether it's electricity or data. This reduction of signal, also called attenuation, is directly related to the length of a cable—the longer the cable, the greater the insertion loss. Insertion loss is also caused by any connection points along a cable link (i.e., connectors and splices).
