Core wire
Aluminum foil
Braided shield

Shielded RJ45 connector
Strip the cable.
Make an incision of 20 mm
in the outer jacket.
Strip off the braided shield and cut
the aluminum foil and unwanted
materials.
When stripping off the outer jacket, take care not to damage the braided shield
or aluminum foil.
Remove the outer jacket.
Arrange the core wires according to the pin assignments and cut them
neatly (exposing a length of 12 mm).

RJ45 connector crimping tool
Insert the arranged core wires into an RJ45 connector according to the pin
assignments and crimp the connector with the crimping tool.
Cut off the exposed braided shield and
materials along the edge of the connector.
Cut off the exposed braided
shield and materials.
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.

•Use the crimping tool to crimp the connector with force.
•After crimping, verify that the connector has been crimped tightly.
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.

Optional: Use a multimeter to measure the impedance of core wires. The impedance
difference between core wires must be less than 5%.
