Installing IFL cables 5–15
Hub installation
Test the IFL cable and connectors as follows:
1. Check each connector: Use a multimeter or continuity tester
to check for continuity (a short circuit) between the center
conductor and the connector body (outer shell).
If the meter or tester does not indicate an open (no
connection), the connector or cable is defective and must be
replaced.
2. Check the connectors and cable:
a. Using a small jumper cable, attach a jumper clip to
the center conductor of the connector on one end of
the cable.
b. Attach the other end of the jumper to the connector
body, so the center conductor and connector body
make electrical contact.
c. At the other end of the cable (at the IDU location),
use a multimeter to measure the resistance between
the center conductor and connector.
Resistance should be less than 10 ohms. If it is
greater than that find and correct the problem.
1. Connect the IFL to the ODU as shown in figure 5-11.

2. Apply electrical tape to the N connector for temporary
protection against moisture contamination.
Do not apply permanent weatherproofing compound or
tape until the HT has been tested and commissioned.
Weatherproofing is covered in section 8.1.
