Using RJ45 Connector Jackets
Use RJ45 cable with connector jackets that are flush with the connector or that have connectors with a
no-snag feature.
Using cable with jackets that are wider than the connectors can cause:
•
Connectors that are not properly aligned with the port.
•
Crowded cable installation, which can cause connectors to pop out of the port.
Figure 6 shows examples of recommended and non-recommended connector jacket types.
