CAUTION
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.
NOTE
The procedures for installing FE/GE optical cables in an APM30H and in an TMC11H are the same. The
following description is based on the procedure for installing a FE/GE optical cable in an APM30H.
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.
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 Figure 6-89.

Step 2 Insert a FE/GE optical cable into the optical module, as shown in Figure 6-90.
