Bind the IF cable first to prevent its type-N connector from being pulled.
Make waterproof curves for the part of the IF cable below the ODU and the part of the IF cable outside the
IDU room.

Connecting the IDU and ODU When the Surge Protector
Is not Installed
If the RG-8U or 1/2
–inch IF cable is used, an IF jumper is required to connect the IF cable and the IF
interface of the IDU, both ends of the IF cable are terminated with type-N connectors. If the 5D IF cable is
used, the 5D IF cable is directly connected to the IF interface of the IDU, One end of the IF cable is
terminated with the type-N connector and is connected to the ODU. The other end of the IF cable is
terminated with the TNC connector.
If the equipment is configured with the IF 1+1 protection, the IF cable of the main ODU must be connected
to the IF jumper of the working IF board, and the IF cable of the standby ODU must be connected to the IF
jumper of the protection IF board.
If the IF boards that provide the XPIC function are used, the IF cable of the ODU that applies the vertical
polarization must be connected to the IF jumper of the IF board that processes vertically polarized waves,
and the IF cable of the ODU that applies the horizontal polarization must be connected to the IF jumper of
the IF board that processes horizontally polarized waves.
