PAIRS of Structured
Cabling
Power over Ethernet (PoE) is a technology that transfer Ethernet signal along with the Power safely over twisted pair cable in Local Area Network (LAN)
Twisted Pair is best suited cabling media to support emerging applications used for data, video and voice communications, as well as simultaneously powering communication equipment, such as wireless access points, cameras and LED lighting etc.

How is power transferred from source to device?

Switch – PSE Access Point – PD Step-1 Sends Probing Voltage looking for a
25 K Ohm resistor
Step-2 PD confirms to PSE if it is valid PD
Step-3 PSE considers connected device as valid PD . Asks
PD to classify itself (Optional)
Step-4 PD confirm Class 3 ( Accordingly power is limited
to 15.4W max)
Step-5 PSE starts sending 50V DC. PD boots up and
Ethernet signal gets established

Poll 2
Out of the below which cable design do you think is best for minimum heat dissipation and
maximum ampacity performance?
a) CAT5e
b) CAT6
c) CAT6A and above
Complex use cases require right cable installation
and design
27Copyright © 2018 Sterlite Tech.
Installation best practices Recommended cable type
Real life experiments?
Smaller cable bundle sizesSmaller bundle sizes help reduce temperature rise
De-rate the maximum channel
lengthKeep temperature rise below 15º
Design pathways to support
airflowUse ventilated trays for better airflow
Open mesh cable trays and ladder racks will improve heat
dissipation
Use Shielded CableShielded products dissipate heat down the length of the
cable and therefore improve capability
Use higher category cablingLarger gauge conductor sizes which are more efficient in delivering power

• A homogeneous cable bundle
consisting of total 19 cables is built.
• Two Layers around the center cable,
where the first layer consists of Six
cables and the second layer consists
of Twelve cables)
• All the eight conductors are then
connected in series and then
connected to the DC power
supply
• Thermocouples are placed on the
cable jacket at various positions
along the cable bundle length in the
bundle as shown below
T1 – Thermocouple placed on the insulation of
the center cable at the midpoint of the bundle
T2 – Thermocouple placed on the jacket of the
center cable at the midpoint of the bundle
T3 – Thermocouple placed on the jacket of the
center cable at a distance of 2 feet (to the left)
from the
midpoint of the bundle
T4 – Thermocouple placed on the jacket of the
center cable at a distance of 2 feet (to the
right) from
the midpoint of the bundle
