Return Loss indicates in copper cabling tests?

Explanation:
Return loss is about reflected energy in a copper link. When the cable, connectors, or terminations aren’t perfectly matched to the source impedance, part of the signal bounces back toward the transmitter. The test measures how much energy is reflected, usually in decibels. A higher return-loss value means less reflection and better impedance matching, which helps preserve signal integrity and reduce problems like interference and standing waves. This concept is different from the total signal loss along the length (attenuation), the amount of noise in the signal, or the theoretical maximum data rate.
