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.
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.
If the fiber optic cables close to a device are too long, coil the excess of the cables and
secure them on the tower.
 A lower-level RU obtains power directly from the external power system, but not from an
upper-level RU using a power cable.
