Testing Twisted Pair Cabling

Short on Twisted Pair Cabling

Figure 9 shows a short between wires 5 and 6. The shorted 
wires flash to indicate the fault. The cable length is 75.4 m.

Note

When there is a short, the far-end adapter and the 
mapping of the unshorted wires are not shown.

Typical Causes of Shorts

Damaged connector.

Damaged cable.

Conductive material stuck beween pins at connector.

Improper connector termination.

Wrong application for cable.
