Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data communication systems, particularly optical communication networks, face challenges in diagnosing and managing complex Pulse Amplitude Modulated (PAM) devices due to insufficient diagnostic data, which hinders accurate high-speed data transmission and error detection beyond 10 Gbits/s.
Innovation Solution
The introduction of new registers in a PAM optical device to store and process additional diagnostic information such as error rates, signal-to-noise ratios, and other parameters, enabling enhanced diagnostic capabilities through direct data processing within the module or transmission to a host for further analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple channels are used to meet high-speed data transmission demands, then data transfer capability is improved, but device complexity increases
Solution Approach 1:
The patent divides the complex optical communication device into multiple functional blocks, each responsible for specific diagnostic tasks. Separate diagnostic blocks monitor different parameters (error rates, signal quality, channel performance) independently, allowing the system to handle multiple channels without proportionally increasing overall complexity.
Solution Approach 2:
The patent adds a new dimension of diagnostic monitoring capability to the existing optical communication device. By incorporating comprehensive diagnostic blocks that operate in parallel with data transmission functions, the system gains enhanced monitoring capabilities without fundamentally redesigning the core transmission architecture.
2Measurement precision
If comprehensive diagnostic information is collected from complex optical devices, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent implements universal diagnostic blocks that can monitor multiple parameters across different channels using the same hardware infrastructure. These diagnostic blocks serve multiple functions: error rate measurement, signal quality assessment, and channel performance monitoring, reducing the need for separate dedicated components for each diagnostic function.
Solution Approach 2:
The diagnostic system is designed to automatically monitor and report device performance without requiring external intervention. The diagnostic blocks continuously assess transmission quality and generate performance data autonomously, reducing the operational complexity despite the comprehensive monitoring capabilities.
