The explanation for split pairs is not very clear and the diagram is wrong. If the diagram is the display of the Fluke tester, Fluke should correct it since it is very misleading. If as in the diagram in the video, blue pair is on pins 4,5 and brown pair is on pins 7,8, then the differential signals will NOT be split and the connection will be fine. A proper split pair diagram should show on pin 5 the blue-wht wire becoming brwn-wht then becoming blue-wht again. And vice versa for pin 7. A split pair means one end of a differential signal goes to one twisted pair and the other end of the differential signal goes to another twisted pair. In other words the differential signal has been split into two different twisted pairs of wire. Split pairs can happen on a manually connectorized cable if one mistakenly transposes the orange wire in position 2 and the green-wht wire in position 3. This transposition must happen on both ends of the cable otherwise it will be a simple wire map failure and not a split pair. As mentioned in the video, continuity checks and wire map tests will not detect a split pair. But the cable will fail a signal quality test. Split pairs can happen in a large installation when an installer uses a cable tracer or a wire mapper tool to try to correct a pair that was punched into a wrong location. You need to commit two errors to make a split pair. It is rare, but I've seen it happen when I used to do structure cabling thirty years ago.
Thanks for paying such close attention! I can assure you that the diagram and the description are both correct. It looks like the diagram on the Versiv screen has confused you a bit. Pins 4 and 5 should be paired together and 7 and 8 as well. What the diagram is showing is that 7 is paired with 4 and 5 with 8 - a splitting of the pairs. The error is made on both ends (as you correctly describe).
Fantastic webinar, thank you very much
Best share indeed
Nicely done

What's with the dulcet tones of men presenting for Fluke? The women sound more assertive and professional.
