WebThis measurement is the same as return loss, which is expressed as a positive value to indicate how much signal was lost by comparing input power to output power versus reflectance that compares output power to the amount of light reflected. For both reflectance and return loss, the further the value is away from zero, the better the results. WebMiss-matched in the system results in insertion loss and return loss. Ideally reflected power must be equal to zero but, in a practical sense, it has some value that can be up to 10 dB or more even after minimizing these losses.

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.) 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 ...
