Optical Burst Error Index Estimation for Communication Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In optical communication systems, reducing the communication setting margin to increase capacity makes it difficult for service providers to grasp the condition of communication quality, especially due to the occurrence of burst errors caused by factors like lightning or earthquakes.
Innovation Solution
A communication device and method that acquire quality information about burst errors in optical communication lines and estimate an index value indicating the degree of influence on communication quality, allowing service providers to adjust settings and maintain stable service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large margin is set to communication settings (SNR, error correction) to ensure error-free communication, then communication quality is improved, but communication capacity is reduced
Solution Approach 1:
The patent dynamically adjusts communication parameters (modulation scheme, code rate, SNR margin) based on real-time channel conditions and burst error characteristics. By changing parameters adaptively rather than using fixed large margins, the system achieves both high reliability and high capacity - when channel conditions are good, it uses aggressive parameters for maximum capacity; when burst errors occur, it adjusts parameters to maintain quality.
2Productivity
If a low margin is set to communication settings to increase communication capacity, then communication capacity is improved, but communication quality becomes difficult to grasp and may deteriorate
Solution Approach 1:
The patent implements a feedback mechanism that monitors burst error characteristics (error rate, error pattern, timing) and uses this information to adjust communication parameters. The burst error information acquiring unit continuously gathers quality data, and this feedback enables the system to maintain optimal communication quality even when operating with low margins for high capacity.
Solution Approach 2:
The system transitions from static communication parameters to dynamic parameter adjustment based on real-time burst error conditions. The communication settings are no longer fixed but adapt continuously to changing channel conditions, allowing the system to operate at high capacity while maintaining quality through rapid parameter changes in response to detected burst errors.
3Productivity
If communication settings are adjusted to increase capacity, then it becomes difficult to grasp communication quality conditions, but this is necessary for diversified service providers
Solution Approach 1:
The patent introduces burst error information as an intermediary metric that bridges the gap between diverse communication settings and quality assessment. Instead of directly measuring complex quality parameters under varying settings, the system uses burst error characteristics (error rate, pattern, timing) as a standardized intermediary indicator that accurately reflects communication quality regardless of the specific modulation scheme or code rate being used.
