Abstract
A monitoring and troubleshooting system to determine whether or not an antenna that is used for receiving wireless weak signals, like base station for cellular wireless communication, is operational. The antenna status condition is signaled over the Fiber Optic (FO) link without interfering the signal during normal operation. When a fault is detected the status at the FO receiver is determined. Then, an indication using special signaling allows a service technician to distinguish if the status fault is antenna failure or antenna disconnect. The present invention will also allow a service technician to determine if there is a FO link failure by use of light intensity monitoring.
