Fiber Optic RF Repeater System 

6.3.1 Recommended 

System Start up Procedure 

•  Verify all RF cables are connected and all unused RF connections terminated with 

50 Ohm terminations. 

•  Verify all Alarm and AC connections are properly made 

•  Connect fiber optic cables.   

•  Apply AC power to system components. 

 

RRU has internal AC power connections that can cause shock if operator is not 
careful.  Always verify the AC Power area is clear of all objects. Do not leave 
objects inside the RRU that can cause dangerous shock hazard. 
 

 
7 Maintenance 

 
This Fiber Optic repeater system does not require scheduled maintenance.  
However, use precautions while installing optical fibers to keep connector surfaces 
clean.  An unclean optical connector surface can damage the internal transceiver 
connector which can degrade system performance and violate Fiber-Span warranty.  
Keep heat dissipating surfaces or vents clean and clear.
