5.2 IF Cable
The IF cable connects the ODU and IDU. The IF cable is used to transport the IF signal, O&M
signal, and -48 V power between the ODU and the IDU.
IF cables are of three types, namely, 5D cable, 1/2-inch cable, and RG-8U cable.
l
If the distance between the IDU and the ODU is less than 120 meters, use the 5D cable.
One end of the 5D cable needs to be terminated with a type-N connector for connecting to
the IF interface of the ODU. The other end of the 5D cable needs to be terminated with a
TNC connector for connecting to the IF interface of the IDU.
l
If the distance between the IDU and the ODU is within 120 meters to 180 meters, use the
RG-8U cable. Both ends of the RG-8U cable need to be terminated with the type-N
connectors for connecting to the IF interface of the ODU and the IF jumper of the IDU,
respectively.
l
If the distance between the IDU and the ODU is within 180 meters to 300 meters, use the
1/2-inch cable. Both ends of the 1/2-inch cable need to be terminated with the type-N
connectors for connecting to the IF interface of the ODU and the IF jumper of the IDU,
respectively.
