NOTICE
Ensure that the exposed shield layer of the power cable is properly tightened using the clip.
Step 2
Connect the connector at the other end of the RRU power cable to the corresponding position
on the power device.
NOTE
l
A DCDU-11B/DCDU-12B can supply power to a maximum of six RRUs. Ensure that the RRU power
cable is connected to one of LOAD0 to LOAD5 ports on the DCDU-11B/DCDU-12B.
l
One EPU can supply power to a maximum of six RRUs. Ensure that the RRU power cable is connected
to one of RRU0 to RRU5 ports on the EPU.
l
When the RRU power cable is connected to the EPU, the blue core wire in the tool-less female connector
(pressfit type) is connected to the upper port on the EPU, and the black/brown core wire is connected
to the lower port on the EPU.
Step 3
Route the cable according to the instructions in
, and then use a cable
tie to bind the cable.
Step 4
Label the installed cable according to the instructions in Attaching a Cable-Tying Label.

9.11 Installing a CPRI Fiber Optic Cable
This section describes the procedure for installing a CPRI fiber optic cable.
Prerequisites
Before the installation, single-mode optical modules can be distinguished from multi-mode
optical modules in either of the following ways:
l
SM and MM labels on an optical module: SM indicates a single-mode optical module, and
MM indicates a multi-mode optical module.
l
Color of the puller on an optical module: Blue indicates a single-mode optical module, and
black or gray indicates a multi-mode optical module.
NOTICE
The optical modules to be installed must match CPRI rates.
Context
l
For RRU3632, A CPRI fiber optic cable transmits CPRI signals between a BBU and an
RRU.
l
For RRU3832, the CPRI fiber optic cable transmits CPRI signals between a BBU and an
RRU or between RRUs. When the fiber optic cable is used for connecting RRUs, the end
