Solution Overview
Problem
The challenge in optical fiber connections is accurately aligning the bevel directions of beveled optical fibers, which is difficult and affects connection quality, leading to increased reflections and loss.
Innovation Solution
A method and tool for aligning the bevel directions of optical fibers by using a connection jig and a front end bevel processing tool, where the optical fibers are sandwiched between elements and connected, ensuring precise alignment of bevel angles and phases, facilitating easy manipulation and reduced reflections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the front end faces of optical fibers are beveled to reduce reflected return light, then connection losses are reduced, but the operation of adjusting bevel directions becomes difficult
Solution Approach 1:
The optical fiber holder is designed with a pre-set bevel direction that matches the bevel direction of the optical connector. This preliminary configuration eliminates the need for difficult adjustment operations during connection, while still achieving low connection losses through proper bevel alignment.
Solution Approach 2:
The optical fiber holder automatically aligns the bevel direction of the inserted optical fiber with the bevel direction of the optical connector through its structural design. This self-aligning mechanism reduces reflected return light and achieves low connection losses without requiring manual adjustment operations.
2Reliability
If bevel directions are accurately aligned to reduce reflections, then connection quality improves, but the alignment operation becomes difficult
Solution Approach 1:
The optical fiber holder is pre-configured with a specific bevel direction that corresponds to the optical connector's bevel direction. This preliminary setup ensures accurate alignment for high connection quality without requiring difficult manual adjustment operations.
Solution Approach 2:
The holder structure automatically ensures proper bevel direction alignment when the optical fiber is inserted. This self-aligning feature achieves reliable connection quality while eliminating complex alignment operations.
3Manufacturing precision
If a fixed structure is used for connector assembly, then manufacturing precision is maintained, but adaptability to different optical fiber thicknesses is reduced
Solution Approach 1:
The optical fiber holder employs a movable structure that can adjust its position and orientation. This dynamic design allows the holder to adapt to optical fibers with different thicknesses while maintaining manufacturing precision through controlled movement and positioning mechanisms.
Solution Approach 2:
The holder structure allows for changes in positional parameters to accommodate different optical fiber thicknesses. By adjusting these parameters, the system maintains assembly precision across various fiber specifications without requiring a completely different fixed structure.
