Open Pairs Failure
Figure 3 shows a wire map of a cable test that fails because wires 4, 5, 7, and 8 are open. The
wires are not connected on the far end and the test limit is set to ≥1000BASE-T (1G) to verify a
4-pair cable. With a test limit set to 10BASE-T or 100BASE-TX, the wire map of the cable test
passes. The length of the wires on the wire map indicates the distance to the open.
