RJ-45 Connector Jackets
Use RJ-45 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 102
shows examples of connector jacket types that are not recommended as well as those that are
recommended.

Radio Frequency Interference
If you use UTP cabling in an installation, take precautions to avoid RF interference. RF interference can
cause degradation of signal quality, and, in an Ethernet network environment, can cause excessive
collisions, loss of link status, or other physical layer problems that can lead to poor performance or loss
of communication.
To prevent RF interference, avoid the following situations:
●
Attaching UTP cable to AC power cables
●
Routing UTP cable near antennas, such as a ham radio antenna
●
Routing UTP cable near equipment that could exhibit RF interference, such as ARC welding
equipment
●
Routing UTP cable near electrical motors that contain coils
●
Routing UTP cable near air conditioner units
●
Routing UTP cable near electrical transformers
In areas or applications where these situations cannot be avoided, use fiber optic cabling or shielded
twisted pair cabling (STP).
