Solution Overview
Problem
In wavelength division multiplexing-based passive optical networks, long-range communication is often disrupted by chromatic dispersion and nonlinear phenomena due to varying output values from optical communication modules, requiring manual site visits for signal attenuation adjustments.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual site visits are used to adjust optical signal levels, then signal attenuation can be properly controlled, but operation complexity and time consumption increase
Solution Approach 1:
The optical communication module autonomously controls its own optical signal attenuation by using the auxiliary management controller to monitor receive light power levels and adjust the transmission attenuator accordingly, eliminating the need for manual intervention at remote sites
Solution Approach 2:
The system implements a feedback mechanism where the auxiliary management controller continuously monitors the receive light power level through the optical reception assembly and uses this information to automatically adjust the transmission attenuator, creating a closed-loop control system that maintains optimal signal levels
2Length of moving object
If optical signal power is increased for long-range communication, then communication distance is extended, but chromatic dispersion and nonlinear phenomena increase
Solution Approach 1:
The system dynamically adjusts the transmission optical signal power based on real-time monitoring of receive light power levels, allowing the communication module to optimize its output power for different transmission distances and conditions, thereby extending communication range while avoiding excessive power that would cause chromatic dispersion and nonlinear effects
Solution Approach 2:
The auxiliary management controller changes the transmission power parameter dynamically by adjusting the transmission attenuator based on monitored receive power levels, enabling the system to adapt to different communication distances and maintain optimal signal quality without fixed power settings
