Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In WDM-based optical communication systems, manually setting wavelengths for optical transceivers is cumbersome and time-consuming, requiring administrator visits and leading to high installation and maintenance costs.
Innovation Solution
An optical transceiver capable of automatically setting wavelengths through a controller that generates and processes transmission and reception wavelength information, using an auxiliary management and control channel to communicate with other transceivers, allowing for self-configured wavelength settings without direct human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual wavelength setting is used, then wavelength configuration can be achieved, but installation and maintenance costs increase and time consumption increases
Solution Approach 1:
The optical transceiver automatically performs wavelength setting by generating test optical signals, receiving response signals from the remote transceiver, and autonomously determining the optimal wavelength combination without requiring administrator intervention. This self-service mechanism eliminates manual configuration costs and time consumption.
Solution Approach 2:
The system performs preliminary wavelength testing by sequentially generating multiple test optical signals at different wavelengths before actual communication begins. This preliminary action allows the transceiver to pre-determine the optimal wavelength setting, avoiding the need for manual configuration during installation or maintenance.
2Ease of operation
If administrator visits installation site for wavelength setting, then wavelength can be configured, but time consumption and operational complexity increase
Solution Approach 1:
The optical transceiver autonomously performs wavelength configuration by generating test signals, receiving responses, and determining optimal wavelengths without requiring administrator visits. This self-service capability dramatically improves operational convenience and eliminates time loss associated with manual wavelength setting.
3Measurement precision
If multiple test optical signals are generated sequentially, then optimal wavelength can be determined, but communication establishment time increases
Solution Approach 1:
The system employs periodic action by sequentially generating multiple test optical signals at different wavelengths in a structured manner. Each test signal is transmitted at a specific wavelength, and the remote transceiver responds to indicate successful reception. This periodic testing approach ensures accurate wavelength determination while maintaining efficient communication establishment through automated feedback.
