Problem
Existing optical communication systems, while providing error-free communication, fail to enhance communication capacity, which is crucial as communication service providers diversify and need to consider both quality and capacity of communication infrastructure.
Innovation Solution
A communication device and method that acquires quality information of optical communication lines, estimates the required communication quality, and controls communication channels to optimize the communication capacity while maintaining the desired quality, using techniques such as adjusting channel configuration, modulation schemes, and error correction processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If error correcting codes are appended to data to provide error-free communication, then communication quality is improved, but communication capacity deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of error correction strength based on real-time communication conditions. The system monitors communication line quality and adapts the error correction process accordingly, switching between strong error correction (for poor conditions) and weak or no error correction (for good conditions), thereby optimizing the balance between communication quality and capacity
Solution Approach 2:
The system changes the parameters of the error correction process dynamically. By adjusting error correction strength as a controllable parameter based on communication line quality metrics, the system can shift between prioritizing reliability (strong correction) and productivity (weak correction), resolving the contradiction adaptively
2Reliability
If communication quality is maintained at error-free level, then service quality is improved, but infrastructure capacity utilization deteriorates
Solution Approach 1:
The patent enables dynamic quality adjustment where the communication quality target is not fixed at error-free level but adapts to infrastructure conditions and service requirements. The system can lower quality standards when capacity is prioritized and raise them when reliability is critical, allowing flexible capacity utilization
Solution Approach 2:
The system applies partial error correction only when necessary based on actual communication needs and line conditions, rather than always applying full error correction. This selective approach preserves infrastructure capacity while maintaining adequate service quality
