Multicore Fiber Splicer Screen Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fusion-splicing multicore optical fibers cannot confirm the guiding state of light for individual cores, leading to potential losses during the splicing process.
Innovation Solution
A fusion splicer is developed with a screen featuring a light guide portion that allows only light from one core to pass through, enabling measurement of leakage light intensity to confirm the guiding state of each core, and a system to adjust the position of the screen to align with specific cores or markers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a screen with light guide portion is introduced to measure leakage light intensity, then measurement precision of light guiding state is improved, but device complexity increases
Solution Approach 1:
The screen is divided into a light guide portion and a light shielding portion, allowing selective measurement of leakage light from specific cores while blocking light from other cores. This segmentation enables precise individual core measurement without requiring complex multi-channel detection systems.
Solution Approach 2:
The screen acts as an intermediary component between the optical fibers and the measurement system. By placing the screen with its light guide portion at specific positions, it mediates the light paths to enable sequential measurement of each core's leakage light intensity without direct complex instrumentation.
2Manufacturing precision
If individual core measurement is implemented, then manufacturing precision of splicing is improved, but measurement time increases
Solution Approach 1:
The screen is pre-positioned at predetermined locations corresponding to each core position before measurement begins. This preliminary positioning allows the measurement system to quickly switch between cores by simply moving the screen to pre-planned positions, rather than calculating and adjusting positions during measurement.
Solution Approach 2:
The screen is designed to be movable between different predetermined positions, allowing dynamic switching between measurement locations for different cores. This dynamic repositioning enables efficient sequential measurement of multiple cores without requiring a fixed complex multi-point detection system.
