How to Do Bi-Directional Averaging
You can use bi-directional results to get higher accuracy for loss
measurements you make with an OTDR. If you upload bi-
directional results to LinkWare software, you can use the bi-
directional averaging utility in LinkWare to calculate an average
loss for both directions. The average value is usually more
accurate than a measurement in one direction.
