Power over Ethernet — Cable and Connectivity Recommendations for PoE
Consider Connection Integrity and Performance
Another consideration with PoE is the potential for damage over time to RJ-45 connectors in the network.
Specifically, when a patch cord is unplugged while the connection is energized, a small electrical arc can occur
between the connector and the plug. While there is no immediate damage (and the arc is not dangerous to
users), it can create pitting on the connector tines and patch cord plug contacts over numerous disconnections,
weakening the integrity of the connection.
Leviton recommends using a connector that is designed to keep the connection point between the mated
connector tines and plug at a distance from the point of arcing damage. Leviton has designed the geometry
of its connectors so that arcing occurs at a different area from the point of contact during data transmission.
Leviton connectors also use a patented retention force technology that maintains contact force between plug
and connector, preventing intermittent disconnects that cause arcing.
As with cable, temperature rise in connectors can also affect channel performance. Leviton engineers tested
Atlas-X1 connectors and patch cords against standards requirements. The connector was tested to the IEC
60512-5-2 Connectors for Electronic Equipment standard. The higher performance in the Atlas-X1 connector is
largely due to its unique metal-body construction. Leviton testing found that using metal in the connector body —
instead of commonly-used ABS plastic — creates a 53 percent improvement in heat dissipation.
