RJ-45 Connector Jackets
Use RJ-45 cable with connector jackets that are flush with the connector or that have connectors with a

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.

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
