Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for testing and distributing informational and parametric data among transmission channels lack efficient mechanisms to handle and replicate signal characteristics, such as optical power levels and signal-to-noise ratios, across multiple channels, which is crucial for accurate testing and communication.
Innovation Solution
A switch matrix system comprising a digital data switch matrix (DDSM) and a parametric data switch matrix (PDSM) that operates in parallel to distribute informational content data and parametric data among instrument modules, enabling the replication of signal characteristics across channels, with the PDSM handling high-speed serial communication of parametric data in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single switch matrix is used to distribute both informational content data and parametric data, then device complexity is reduced, but measurement precision and reliability of signal characteristic replication deteriorate
Solution Approach 1:
The patent divides the switching system into two separate switch matrices: a first switch matrix for informational content data and a second switch matrix for parametric data. This segmentation allows each matrix to be optimized for its specific data type, ensuring high-speed serial communication for parametric data while maintaining overall system functionality, thereby resolving the contradiction between device complexity and measurement precision.
2Measurement precision
If high-speed serial communication is implemented for parametric data, then measurement precision and real-time processing capability are improved, but device complexity increases
Solution Approach 1:
The system segments parametric data handling into a dedicated second switch matrix that operates independently with high-speed serial communication capabilities. This allows real-time processing of signal characteristics without complicating the overall system architecture, as each matrix handles its specific data type with appropriate processing speed.
Solution Approach 2:
The second switch matrix is designed with multi-functionality to handle various parametric data types (optical power levels, signal-to-noise ratios, etc.) through a unified high-speed serial communication interface, reducing the need for multiple specialized components and thereby limiting the increase in device complexity.
3Productivity
If parallel operation of two switch matrices is implemented, then productivity and efficiency of data distribution are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent implements parallel operation of two segmented switch matrices where the first handles informational content data and the second handles parametric data. This segmentation enables simultaneous processing of different data types, improving overall productivity and efficiency of the data distribution system.
Solution Approach 2:
The system merges the functionality of two separate switching operations into a coordinated parallel architecture, where both switch matrices operate simultaneously but independently. This combining of parallel operations achieves high data distribution efficiency while managing device complexity through standardized interfaces and modular design.

AI summary
An example system includes circuitry to receive an input signal, to provide a related signal based on informational content of the input signal, and to obtain parametric data associated with the input signal. The parametric data represents one or more signal characteristics other than the informational content. The example system also includes a first switch that is configurable to provide first data based on the related signal to one or more first channels of the system; and a second switch that is configurable to provide second data based on the parametric data to one or more second channels of the system.
