Prepare the following tools.
RJ45 connector crimping tool
Diagonal pliers
Prepare an outdoor network cable
and shielded RJ45 connectors.

Core wire
2.
Aluminum foil
3.
Braid shield
4.
Outer jacket
5.
Shielded RJ45 connector
Strip the cable.
Length of the stripped
cable: 20 mm
Strip off the braid shield and cut
the aluminum foil and unwanted
materials.
When stripping off the outer jacket, take care not to damage the braid 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).

Cut the core wires neatly.
Length of each exposed core wire: 12 mm

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 braid shield and materials
along the edge of the connector.

Outdoor network cable
Terminate a connector on the other end of the network cable, and then test the cable
for continuity using a network cable tester.

In addition to Ethernet services, the P&E port of the RTN 380H receives P&E 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 380H. In this case, you need to make a network cable based on the pin
assignments of the two P&E ports.
Optional: Use a multimeter to measure the
impedance of core wires. The impedance
difference between core wires must be less
than 5%.

•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.
Preparing an RSSI Test Cable
Terminate one end of an outdoor network cable with an RJ45 connector
by following instructions in "Terminating an Outdoor Network Cable with
Shielded RJ45 Connectors."
Blue core wire
White and brown
core wire
Strip the other end of the cable, remain the core wire for pin 4 (blue) and
that for pin 7 (white and brown), cut off the other core wires, and wrap
this end.
