Abstract
A fiber optic status monitoring system for a fiber optic cable television system is disclosed in which a computer serially polls a plurality of optical transmitter modules, optical receiver modules, or other cable television component modules to determine their operation. Each of the monitored components at a given location are connected together together by a common bus. In addition, each of the transmitter modules and the receiver modules include a monitoring/control unit. The computer transmits a command signal to an interface unit. The interface unit transmits the command signal to the transmitter modules via a bus. The command signal is modulated at the interface unit and transmitted over a bidirectional link. The modulated command signal is received and demodulated by a status monitoring interface unit. The status monitoring interface unit distributes the command signal to each of the monitored modules at that location. If the command signal is a query command signal, a monitoring unit transmits information on the operation of the module. If the command signal is a control command signal, a monitoring unit serves to supply control signals to the module.
