WebDetermining Reflection Measurement Accuracy. The Return Loss Uncertainty Chart (Figure 4) provides a quick method of determining measurement uncertainty for different devices. To use the chart, find the measured return loss of the device on the X axis at the bottom of the graph, move up to the first intersection of the directivity (stamped on ... WebMeasuring Reflectance And Optical Return Loss Reflectance In an OTDR, the peak that identifies a reflective event is measured and reflectance calculated. Higher peaks indicate higher reflectance. In order to measure reflectance, the peak must not saturate the OTDR receiver, indicated by a flat-topped reflectance peak (below.)
