Optical Amplifier Configuration via SRS Power Transfer Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In complex optical transmission networks, the SRS effect leads to degradation of system performance by transferring optical power from high-frequency to low-frequency channels, making it challenging to calculate the configuration of optical amplifiers effectively and reduce the impact range and time of noise on the system.
Innovation Solution
A method that acquires initial input power of an optical cable, calculates output power at each channel section based on cable loss, and uses this output power as a boundary condition to determine input power adjustments due to the SRS effect, thereby calculating a first parameter value for optical amplifiers to overcome SRS-induced damage and optimize system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the band is continuously evolved to improve transmission capacity of optical fibers, then transmission capacity is improved, but the influence of noise on the system becomes more complex
Solution Approach 1:
The optical cable is divided into multiple sections, with optical amplifiers placed at specific sections. This segmentation allows the system to manage noise influence locally at each section rather than treating the entire transmission line as a single complex system, making noise calculation and management more tractable while maintaining high transmission capacity.
Solution Approach 2:
The patent implements a feedback mechanism where the output power of each channel at the end of a section serves as a boundary condition to calculate the input power at the beginning of that section, accounting for SRS effects. This feedback loop enables accurate noise influence calculation and optimization of amplifier configuration even as the band evolves to increase transmission capacity.
2Power
If optical power is transferred from high-frequency channel to low-frequency channel due to SRS effect, then power transfer occurs, but system performance degrades
Solution Approach 1:
The patent calculates the SRS-induced power transfer between channels in advance and uses this information to pre-adjust the configuration of optical amplifiers. By compensating for the expected SRS effect beforehand, the system counteracts the performance degradation before it occurs, maintaining reliability despite the inherent SRS power transfer phenomenon.
Solution Approach 2:
The patent adjusts the input power parameters of different channels based on calculated SRS effects. By modifying the power distribution parameters across channels and optimizing amplifier gain settings, the system compensates for SRS-induced power transfer and maintains overall system performance.
3Productivity
If configuration of optical transmission network is calculated using traditional methods, then calculation is performed, but accuracy is insufficient for complex networks
Solution Approach 1:
The patent divides the optical transmission network into multiple sections with discrete amplifiers, allowing the configuration calculation to be performed section by section. This segmented approach maintains computational efficiency while improving accuracy by locally optimizing each section based on boundary conditions from adjacent sections, rather than attempting to calculate the entire complex network as a single system.
Solution Approach 2:
The patent uses a feedback-based calculation method where the output power at the end of each section serves as a boundary condition for calculating the input power at the beginning of that section. This feedback mechanism iteratively refines the configuration calculation, achieving high accuracy for complex networks while maintaining reasonable computational speed through structured iteration.
