Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Defects in optical cables and SFP modules used for transmitting image data to large-screen display apparatuses, such as those found in digital signage, can lead to data loss and transmission failures, especially due to long-term use and environmental factors, necessitating costly and time-consuming replacements.
Innovation Solution
An electronic apparatus with processors that adjust the driving voltage of image data to generate test data, allowing for proactive identification of potential defects in SFP modules and optical cables by comparing received test data with generated verification data, using methods like pre-emphasis and de-emphasis to predict future defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If optical cable and SFP module are used for transmitting image data over long distances, then transmission capability is improved, but reliability deteriorates due to progressive defects from long-term use
Solution Approach 1:
The system performs preliminary defect prediction by transmitting test data with adjusted voltage levels through the optical cable and SFP modules before actual image data transmission. This allows early detection of progressive defects in the optical components, enabling maintenance before complete failure occurs, thus maintaining reliability over long transmission distances
Solution Approach 2:
The system establishes a feedback loop where test data is transmitted through the optical cable and SFP modules, received, and analyzed to determine connection status. This continuous monitoring provides real-time feedback on the health of the optical connection, allowing proactive replacement of defective components
2Use of energy by moving object
If standard voltage level is used for image data transmission, then power consumption is reduced, but defect detection capability is insufficient
Solution Approach 1:
The system changes the voltage level parameter of test data to be different from standard image data transmission levels. By transmitting test data at adjusted voltage levels and analyzing the received signal characteristics, the system can detect progressive defects in optical cables and SFP modules that would not be apparent during normal operation
3Reliability
If optical cable and SFP modules are replaced proactively, then transmission reliability is improved, but cost and complexity increase
Solution Approach 1:
The system performs self-diagnosis by automatically transmitting test data, receiving the signal, analyzing connection status, and determining whether optical components require replacement. This self-service capability enables proactive maintenance based on actual condition rather than fixed schedules, improving reliability while managing complexity through automation

AI summary
An electronic apparatus includes: a first interface configured to be connected to a first small form-factor pluggable (SFP) module provided at an end of an optical cable; a second interface configured to be connected to a second SFP module provided at a second end of the optical cable; memory storing instructions; and one or more processors configured to execute the instructions to: identify a driving voltage corresponding to image data; change a level of the driving voltage of the image data to generate test data; and based on the test data transmitted through the first interface being received by the second interface, identify whether the first SFP module, the second SFP module, or the optical cable are progressively defective based on the received test data and the image data.
