NRT’s Joint Probability Density Function Calculator (NRT-JPDFC)

NRT’s Joint Probability Density Function Calculator (NRT-JPDFC) generates a topographical contour map of the PMD probability in 2-D PMD space, namely SOPMD vs. DGD. Each generated contour on the graph shows the probability of the PMD state to be found within the contour. Hence the 50% contour (black innermost contour) shows the PMD states where the fiber will be half of the time. The red outermost contour designates the PMD region 99.997% of the time. Using the cursor, the time spent at any PMD state can be determined.
