If a right angle type-N connector is used to
connect the surge protector to the ODU,
waterproof the entire right angle type-N
connector and the interfaces on both the ends.

Connecting the IDU and ODU When the Surge Protector
Is Installed(NA)
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 surge protector.
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 applie s the
horizontal polarization must be connected to the IF jumper of the IF board that processes horizontally polarized waves
.
For the installation of the surge protector, see page 40.
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.
