Light Emitter Control Circuit for Optical Network Fault Prevention

The patent applies preliminary action by monitoring the electrical data signal before it reaches the light emitter and detecting faulty operation conditions in advance. The system continuously checks for abnormal patterns (such as continuous high-level signals indicating faults) and deactivates the light emitter before permanent damage or network-wide blocking can occur, preventing harmful effects rather than reacting to them after they manifest

The patent implements feedback by continuously monitoring the electrical data signal fed to the light emitter and using this information to control the emitter's operation. The monitoring circuit provides real-time feedback about the data signal state, and when faulty patterns are detected (such as sustained logic high levels indicating circuit failure), the system responds by deactivating the light emitter, creating a closed-loop control system that prevents harmful effects

The patent applies self-service by having the monitoring circuit utilize the existing electrical data signal that is already present in the system for normal operation. Rather than requiring separate test signals or additional sensors, the system monitors the actual data signal being transmitted, allowing the data communication infrastructure to serve its own monitoring function. This reduces additional hardware complexity while maintaining reliable fault detection

The patent implements universality by designing the monitoring circuit to perform multiple functions: it continuously monitors the electrical data signal for fault detection, identifies faulty operation patterns, and controls the light emitter deactivation. This multi-functional approach consolidates what could be separate systems into a single integrated circuit, reducing overall device complexity while maintaining comprehensive fault detection and prevention capabilities
