Power over Ethernet — Cable and Connectivity Recommendations
Reduce the Number of Cables per Bundle
Separating large cable bundles into smaller bundles or avoiding tight bundles
will reduce temperature rise. For example, TIA tested the temperature of a
bundle of 91 cables, and three bundles of 37 cables. The temperature in the
center of a 91 cable bundle was higher than the worst case temperature in
center point of three bundles. Physically separating the three bundles from
each other further reduced the maximum temperature.
Install Shielded Cabling or UTP with Isolation Wrap
UTP cable with patented isolation wrap features separations in the
wrap to prevent a current from flowing along the length of the cable.
These cables radiate heat better than traditional UTP cable, minimizing
the cables temperature rise. UTP cable with a segmented isolation wrap
provides additional alien crosstalk suppression, but eliminates the need
for grounding and bonding required with shielded cabling.
