3.4.2 Preparing and Connecting the IDU-ODU Cable
1
Unscrew the top nut from the Service Box.
2
Route a straight-through Cat. 5 Ethernet cable (8-wire, 24 AWG) through both the top nut and
the body of the Service Box.
3
Insert and crimp the RJ-45 connector. Refer to the cable preparations instructions described
below.
4
Connect the Ethernet cable to the ODU RJ-45 connector.
5 Attach the Service Box to the ODU and tighten the top nut. Make sure that the external jack of
the cable is well inside the Service Box to guarantee good sealing.
6 Route the cable to the location selected for the indoor equipment. It is recommended to attach a
lightning arrestor to the cable immediately before it enters the building.
7
Assemble an RJ-45 connector on the indoor end of the ODU cable. Refer to the pin assignment
and color codes in standard cables described below.
IDU-ODU Cable Preparation:
Use a crimp tool for RJ-45 connectors to prepare the wires. Insert them into the appropriate pins and
use the tool to crimp the connector. Make sure to do the following:
„
Remove as small a length as possible of the external jacket. Verify that the external jacket is
well inside the sealing cover when connected to the unit, to ensure good sealing.
„
Pull back the shield drain wire before inserting the cable into the RJ-45 connector, to ensure a
good connection with the connector's shield after crimping.
The IDU-ODU cable provides pin-to-pin connection on both ends.
The following figure shows the required wire pair connections.
