RJ-45 Connector Jackets

Use cable with RJ-45 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 13 shows examples of connector jacket types that are not recommended as well as those that are
recommended.

Radio Frequency Interference

If you use unshielded twisted pair (UTP) cabling in an installation, take precautions to avoid radio
frequency (RF) interference. RF interference can cause degradation of signal quality, and, in an Ethernet
