Step 2 Connect the RJ45 connector at one end of the Ethernet cable to the CPRI_E0 port on the pRRU
panel.
Step 3 Optional: Connect the RJ45 connector at the other end of the Ethernet cable to the output port
of the Extender. Then, connect the RJ45 connector at one end of another Ethernet cable to the
input port of the Extender.
Step 4 Connect the RJ45 connector at the other end of the Ethernet cable to any port ranging from
CPRI_E0 to CPRI_E7 on the RHUB panel based on the engineering design, as shown in
4-32.

The performance of an optical module that is exposed to the air for more than 20 minutes may
be abnormal. Therefore, you must insert a fiber optic cable into an unpacked optical module
within 20 minutes.

NOTE
The Extender can be used to lengthen the distance between the RHUB and the pRRU connected using the
Ethernet cable. If the Extender is used, the Ethernet cable is divided into two parts, one between the RHUB
and the Extender and the other between the Extender and the pRRU.
Multi-mode optical modules for CPRI ports are labeled MM and each has a black or gray
puller.
Single-mode optical modules are labeled SM and each has a blue puller.
For details about the connection of CPRI optical cables, see CPRI Networking in LampSite
Technical Description and CPRI Optical Fiber in LampSite Hardware Description.
An optical module to be installed must match the rate of its corresponding port.
