Optical Transceiver Diagnostic Analyzer for Real-Time Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional host equipment lacks the ability to easily access and convey diagnostic data from optical transceivers, making it difficult for network administrators to determine the status of individual links and troubleshoot complex systems.
Innovation Solution
An analyzer device that interfaces with an optical transceiver's diagnostic communication port, allowing real-time access and modification of transceiver operational characteristics and data without interrupting normal operation, enabling real-time interrogation, adjustment, and reprogramming of transceiver settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional host equipment is used to access diagnostic data, then the transceiver can operate normally, but the ability to access and convey diagnostic data is poor
Solution Approach 1:
The patent introduces a dedicated diagnostic interface as an intermediary between the transceiver's controller and the host equipment. This interface includes a diagnostic data output terminal and a controller that can selectively communicate diagnostic information, serving as a mediator that enables reliable data access without requiring complex modifications to the host system.
Solution Approach 2:
The diagnostic data communication is segmented into distinct functional components: a diagnostic data output terminal for data extraction, a controller for managing the communication protocol, and a host interface for receiving the data. This segmentation allows the diagnostic function to be isolated and optimized independently from the main transceiver operation.
2Loss of time
If diagnostic data access requires additional equipment or complex procedures, then the transceiver structure remains simple, but the time required for troubleshooting increases
Solution Approach 1:
The diagnostic interface is pre-configured within the transceiver during manufacturing, with the controller programmed to automatically make diagnostic data available through the dedicated terminal. This preliminary setup eliminates the need for network administrators to perform complex procedures or use additional equipment during troubleshooting, as the diagnostic capability is already in place and ready for immediate use.
3Productivity
If real-time access to transceiver parameters is enabled, then troubleshooting efficiency improves, but the risk of interrupting normal operation increases
Solution Approach 1:
The diagnostic controller implements a feedback mechanism that allows the host equipment to query diagnostic parameters in real-time without interfering with the transceiver's normal data transmission. The controller selectively provides diagnostic information based on host requests, enabling continuous monitoring while maintaining the reliability of the optical connection through proper protocol management.
Data Source
AI summary
Exemplary embodiments of the invention relate to an analyzer device configured to interface with an optical transceiver module having a diagnostic communications port, wherein the port is configured to access diagnostic and other data contained within the transceiver controller via a backdoor interface. Controller data, including operational parameter values and module setup values, is accessible while the transceiver operates in conjunction with an external host and may be retrieved, and sometimes modified, in real time without interrupting normal transceiver operation or suspending the transmission of data over optical fibers. The analyzer device accesses the data via the diagnostic communications port on the outside of the transceiver module.
