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.
NOTE
l A lower-level RRU obtains power directly from the external power system, but not from an upper-
level RRU using a power cable.
l The RRU3642 is a single-mode RRU. It only supports the cable connections shown in
Figure 8-10.
l The RRU3642 does not support the inter-RRU cable connection shown in
shows the cable connections for a single RRU in the single-mode scenario.
