Figure 4-2 shows the IFL and lightning arrestor. A lightning
arrestor is required on the roof at the IFL building
penetration point.
Figure 4-2 shows how the IFL cable is installed in two segments
to accommodate the lightning arrestor:
• One segment from the IDU to the rooftop lightning arrestor
• One segment from the lightning arrestor to the ODU

Because the IFL cable is installed in two segments, it is cut and
terminated (with an N–type connector) in four locations, as shown
