1Quantity of substance
If wavelength division multiplexing technique is adopted to increase transmission capacity, then transmission capacity is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary actions by automatically acquiring transmission characteristics information before signal transmission, and uses this information to pre-configure optimal settings for wavelength, band, and other parameters. This preliminary configuration eliminates the need for manual optimization setup, thereby handling increased transmission capacity through WDM without proportionally increasing operational complexity
Solution Approach 2:
The optical transmission device performs self-service by automatically acquiring transmission characteristics information and using it to self-configure optimal transmission parameters. The device autonomously determines wavelength settings and band configurations based on the acquired information, eliminating manual intervention and reducing operational burden despite increased system capacity
2Reliability
If manual optimization of equipment is performed for long-distance transmission, then transmission reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The system implements self-service by automatically acquiring transmission characteristics information specific to the optical transmission line and autonomously determining optimal transmission parameters. This eliminates manual optimization work while maintaining high transmission reliability through scientifically determined settings for wavelength, band, and other critical parameters
Solution Approach 2:
The system uses feedback by acquiring transmission characteristics information from the actual optical transmission line conditions and using this feedback to automatically adjust and determine optimal transmission parameters. This closed-loop approach ensures reliable long-distance transmission without manual intervention by continuously adapting settings based on actual line characteristics
3Ease of operation
If automatic configuration is implemented, then ease of operation is improved, but measurement precision may deteriorate
Solution Approach 1:
The system acquires transmission characteristics information through feedback from the actual optical transmission line, using this precise measured information as the basis for automatic configuration. This ensures that automated settings are based on accurate measurements of the specific transmission medium, maintaining measurement precision while achieving ease of operation
Solution Approach 2:
The system replaces manual measurement and configuration operations with automated optical measurement and electronic configuration processes. The automatic acquisition of transmission characteristics information and subsequent parameter determination maintains precision by using scientific measurement methods while eliminating manual errors inherent in manual configuration processes
