Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual adjustment of optical signal intensity is performed, then signal quality can be maintained, but adjustment complexity and time consumption increase
Solution Approach 1:
The optical communication system performs self-diagnosis and self-adjustment of span loss and intensity difference through automated monitoring and control mechanisms. The control apparatus automatically adjusts the optical signal parameters based on monitored values, eliminating the need for manual intervention while maintaining signal quality.
Solution Approach 2:
The system implements feedback control by monitoring the actual span loss and intensity difference values, comparing them against target values, and automatically adjusting the optical signal parameters. This closed-loop control ensures signal quality is maintained while reducing adjustment complexity.
2Productivity
If automated control is implemented, then adjustment efficiency improves, but system complexity increases
Solution Approach 1:
The control apparatus performs multiple functions including monitoring span loss, monitoring intensity difference, controlling optical signal parameters, and managing the overall adjustment process. This multi-functional design improves adjustment efficiency while managing system complexity through integrated control.
3Reliability
If continuous monitoring is performed, then signal quality is maintained, but energy consumption increases
Solution Approach 1:
The control apparatus performs monitoring and adjustment operations on predetermined cycles rather than continuously. This periodic action maintains signal quality through regular checks while reducing energy consumption by keeping the system in a lower-power state between monitoring intervals.

AI summary
A control apparatus performs: span loss adjustment processing of adjusting a span loss of a first optical signal based on first and third intensities, and adjusting a span loss of a second optical signal based on second and fourth intensities by controlling an optical signal adjustment unit; and intensity difference adjustment processing of adjusting the intensity difference between the first and second optical signals after a span loss adjustment in a second optical communication apparatus by controlling first and second intensity adjustment units. The control apparatus performs the span loss adjustment processing and the intensity difference adjustment processing as an initial setting operation after output of a third optical signal from a first optical communication apparatus starts and performs a monitoring operation of repeating the span loss adjustment processing and the intensity difference adjustment processing on a predetermined cycle after the initial setting operation ends.
