Figure 9-7 FE/GE cables routed through the cabinet
l If fiber optic cables need to be routed on the tower platform, lay out the cables on the
guardrail with the shortest distance and route the cables along the guardrail.
l If fiber optic cables need to be routed close to a device on the tower, secure the cables to
the guardrail or pole with cable clips. The device cannot be far away from the position for
securing the cables.
l If the fiber optic cables close to a device are too long, coil the excess of the cables and
secure them on the tower.
