Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical communication devices configured by combining optical signal processing units face challenges in setting appropriate mask settings due to fixed firmware configurations, which do not accommodate the varying functions achieved by different combinations of internal units.
Innovation Solution
An optical communication device with multiple optical signal processing units, each equipped with processing, output, and detection means, where a reception means selectively outputs anomaly notifications based on mask settings, ensuring that notifications from units with enabled mask settings are suppressed, while those without are forwarded externally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mask setting is written in firmware of each communication device, then the alarm masking function can be implemented, but the mask setting cannot be appropriately adjusted for various functions achieved by different combinations of optical signal processing units
Solution Approach 1:
The mask setting is changed from a static firmware configuration to a dynamic setting that can be adjusted based on the actual combination of optical signal processing units. The reception means dynamically determines which anomaly notifications to output based on the detected unit combinations, allowing the masking behavior to adapt to different functional configurations without requiring different firmware versions.
Solution Approach 2:
The invention changes the parameter of mask setting from being fixed in firmware to being可变 based on unit combination. By making the mask setting dependent on the detected combination of optical signal processing units, the system can appropriately suppress or output anomaly notifications according to the actual functional configuration, resolving the contradiction between adaptability and firmware complexity.
2Adaptability or versatility
If a communication device is developed with one type of hardware provided with a plurality of function blocks, then the number of hardware types is reduced, but the fixed firmware mask setting cannot accommodate the varying functions achieved by different combinations of function blocks
Solution Approach 1:
The reception means dynamically adjusts the anomaly notification output based on the detected combination of optical signal processing units. When certain units are combined, the system dynamically determines whether to output anomaly notifications from specific units, ensuring that the reliability of anomaly notification matches the actual functional configuration while maintaining hardware versatility.
Solution Approach 2:
The invention introduces a feedback mechanism where the reception means detects the combination of optical signal processing units and uses this information to determine the appropriate mask setting. This feedback loop ensures that anomaly notifications are handled accurately according to the actual functional configuration, maintaining reliability while supporting hardware versatility.
3Loss of information
If anomaly notifications from all optical signal processing units are output to outside, then complete anomaly information is provided, but unnecessary alarms increase when mask settings should be applied
Solution Approach 1:
The invention changes the parameter of anomaly notification output from a fixed state (always output or never output) to a variable state that depends on the combination of optical signal processing units. Based on the detected unit combination and corresponding mask settings, the reception means selectively outputs or suppresses anomaly notifications, ensuring information completeness while avoiding unnecessary alarms.
Solution Approach 2:
The invention applies different quality of anomaly notification output to different optical signal processing units based on their specific combinations. Instead of uniformly outputting or suppressing all notifications, the reception means applies local quality control by determining which specific units' notifications should be output based on the mask settings corresponding to the detected combination, thus avoiding unnecessary alarms while maintaining information completeness.

AI summary
In this optical communication device, the multiple optical signal processing units are provided on one optical path; and on the basis of a mask setting that is set by a specific optical signal processing unit, which is among the multiple optical signal processing units and includes the detection unit that has detected the failure, for a next-stage optical signal processing unit connected to the optical path after the specific optical signal processing unit, the reception unit does not output, to the outside, a failure notification from the detection unit provided in the optical signal processing unit for which the mask setting is set and outputs, to the outside, a failure notification from the detection unit provided in any of the optical signal processing units for which the mask setting is not set.
