One key point to consider in Bi-Directional testing is the testing of dissimilar connector styles, i.e. SC to LC. During referencing the launch and receive cables need to be connected and if they aren’t the same they can’t be connected using a standard adapter. There are hybrid adapters, but these don’t provide the best mating and can introduce high losses during the referencing which can be inflated, or maybe it’s more appropriate to say they deflate (watch out Patriot’s fans) the measured readings. In other words, when you artificially increase the amount of loss during reference, you get artificially better and inaccurate test results.
