Return Loss
Return Loss : A measure of impedance mismatch indicated by a return echo signal reflection. It is often referred to as "RL" and it measures the ratio between the transmitted signal strength and the signal reflected back to the transmitting end. Like attenuation, excessive return loss indicates reduced signal strength at the receiver end and it can indicate a mismatched impedance at some point along the cable link. Return Loss is reported as a dB value for each pair, from each end. A value of 20 dB or higher for UTP is very good and a value below 10 dB causes a large reflection of signal back to the source and is not good. The IDEAL LT8000 Series provides this measurement
