You have recently run a 50 meter network connection across the building, and now you’d like to make sure that the punchdowns and crimps have connected the correct pins on each side. Which of these tools would be the best way to confirm your wiring map?
B) Loopback plug
C) Cable tester
D) Null-modem plug
E) Have one person yell while you listen on the other side
The answer: C) Cable tester
Although a multimeter can provide some basic continuity testing, it’s a bit more difficult when the wiring is already in the ceiling and the two ends are a far distance apart. Cable testers are specially designed with an intelligent testing device on one side of the cable, and a remote probe on the other side of the cable.
