Installing a FE/GE Optical Cable
This section describes the procedure and precautions to be taken for installing a FE/GE optical
cable.
Context

l
The performance of an optical module that is exposed to the air for more than 20 minutes may
be abnormal. Therefore, you must insert an fiber optic cable into an unpacked optical module
within 20 minutes.
Procedure
Step 1 Turn the puller of an optical module outwards, and then insert the optical module into the SFP0
or SFP1 port on the LMPT, as shown in
Issue 06 (2011-09-15)
The single-mode optical module is labeled "SM" and multi-mode optical module is labeled
"MM".
If the puller of an optical module is blue, the module is a single-mode optical module. If
the puller of an optical module is black or grey, the module is a multi-mode optical module.
The optical module to be installed must have a matching rate with the corresponding CPRI
port.
CAUTION
NOTE
When an LTE only base station uses FE/GE transmission, FE/GE optical cables are usually used for data
transmission. The following description is based on the configuration of an LTE only base station.
SFP0 and FE/GE0 ports on an LMPT are used for one GE input. Therefore, they cannot be used
simultaneously.
SFP1 and FE/GE1 ports on an LMPT are used for another GE input. Therefore, they cannot be used
simultaneously.
