Optical Transponder Labeling for Port Administration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In optical transmission systems, system administrators face cumbersome administration tasks due to the need to constantly update cross-connect information across terminal stations when port specifications change, requiring synchronization of input and output port information between stations.
Innovation Solution
The implementation of optical transmitters, receivers, and transponders that utilize client and line ports with label providing and terminating mechanisms to automatically identify and connect transmission destinations, eliminating the need for manual cross-connect administration by using labels to direct client signals through the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cross-connect information administration is used to connect client ports with line ports, then connection accuracy is maintained, but administrative burden and time consumption increase significantly
Solution Approach 1:
The system enables self-service automation where the optical transmitter automatically adds labels to client signals and the optical receiver automatically extracts and processes these labels to establish cross-connect relationships. This eliminates the need for manual administration by system administrators, allowing the system to manage its own port connections autonomously.
Solution Approach 2:
Labels serve as intermediaries between client ports and line ports. Instead of direct manual configuration, the label providing means attaches identification information to signals, and the label terminating means at the receiving end uses these labels to automatically establish connections, simplifying the administration process.
2Adaptability or versatility
If port specifications are changed to improve system flexibility, then adaptability increases, but cross-connect information synchronization complexity increases
Solution Approach 1:
When port specifications change, the system automatically updates cross-connect information through the label mechanism. The optical transmitter re-labels affected signals and the optical receiver automatically adjusts connections based on new label information, eliminating the need for manual synchronization and reducing management complexity despite increased flexibility.
Solution Approach 2:
The label information acts as a dynamic parameter that automatically adapts when port specifications change. By changing the label content rather than the entire cross-connect configuration, the system maintains simplicity while allowing flexible port specification changes.
3Reliability
If detailed cross-connect information is tracked to ensure accurate signal routing, then connection reliability is improved, but information management burden increases
Solution Approach 1:
The essential routing information is extracted from complex cross-connect data and embedded directly into labels attached to client signals. This separates the critical routing identifier from the overall system configuration, allowing reliable routing through simple label matching while reducing the burden of managing detailed cross-connect information tables.
Solution Approach 2:
Instead of storing and managing complex cross-connect relationship data, the system creates simplified label copies containing only the essential destination identification. These label copies travel with signals and enable reliable routing without requiring the receiving end to maintain comprehensive cross-connect information.

AI summary
An optical transmitter includes: a plurality of client ports configured to receive a client signal from an end user device; a plurality of line ports configured to generate a line signal in which the client signal is stored, and transmit the line signal to an optical receiver; a switch configured to connect the plurality of client ports with the plurality of line ports; and a label provider configured to provide the client signal with a label for identifying a transmission destination in the optical receiver.
