Terminating an Outdoor Network Cable with Shielded RJ45 Connectors
Prepare an outdoor network cable
Prepare the following tools.

Insert the arranged core wires into an RJ45 connector according to the pin
assignments and crimp the connector with the crimping tool.
Crimp the RJ45
connector.
Pin assignments of an RJ45 connector
•Before crimping, ensure that the core wires are fully inserted in the RJ45
connector.
•Use the crimping tool to crimp the connector with force.
•After crimping, verify that the connector has been crimped tightly.
Optional: Use a multimeter to measure the impedance of core wires. The impedance
8
difference between core wires must be less than 5%.

in the outer jacket.
When stripping off the outer jacket, take care not to damage the braided shield
or aluminum foil.
Cut off the exposed braided shield and
materials along the edge of the connector.

Strip off the braided shield and cut
the aluminum foil and unwanted
materials.
Cut the core wires neatly.
Terminate a connector on the other end of the network cable, and then test the cable
for continuity using a network cable tester.
The pin assignments of the connectors at the two ends must be the same. Outdoor
network cables are straight-through cables.

cable
In addition to Ethernet services, the P&E port of the RTN 360 receives P&E (power over Ethernet)
signals from power sourcing equipment. An outdoor straight-through cable is used to connect
the P&E port and power sourcing equipment.
The pin assignments of the P&E port on some Ethernet power supply equipment may be different
from those on the RTN 360. In this case, you need to make a network cable based on the pin
assignments of the two P&E ports. For example, if the BTS3902E or BTS3202E supplies power over
Ethernet to the RTN 360, an outdoor crossover cable needs to be made.
