Optical Fiber Bundling Member Width-to-Thickness Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical fiber cable bundling methods using bundling members with a width greater than the thickness can cause twisting and entanglement issues, leading to potential fiber breakage and increased transmission loss.
Innovation Solution
An optical fiber unit design where bundling members are wound on the outer circumference of the fiber bundle in an S-Z configuration with a width-to-thickness ratio of less than 20, alternately reversing the winding direction and joined at sections, using a smaller width-to-thickness ratio to minimize twisting and entanglement, and employing adhesive or heat-sealing for joining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If bundling members with width greater than thickness are used to bundle optical fibers, then the optical fiber bundle can be effectively bundled and differentiated, but the bundling members twist at sections where winding directions are reversed, causing potential fiber breakage
Solution Approach 1:
The patent changes the geometric parameters of the bundling member by specifying that the width-to-thickness ratio should be 20 or less. This parameter modification prevents the bundling member from twisting when winding direction is reversed, thereby eliminating the risk of fiber breakage while maintaining effective bundling capability
Solution Approach 2:
The patent introduces asymmetry in the winding configuration by reversing the winding direction at specific sections. By combining this asymmetric winding with the constrained width-to-thickness ratio, the design achieves stable bundling without the twisting problems that would occur with conventional symmetric wide bundling members
2Ease of operation
If bundling members are wound in an S-Z configuration with reversed winding directions, then workability when taking out optical fiber is improved, but the joined parts may become upright and entangle with other fiber bundles
Solution Approach 1:
The patent modifies the geometric parameter of the bundling member by constraining the width-to-thickness ratio to 20 or less. This parameter change ensures that when the winding direction is reversed in an S-Z configuration, the joined parts remain flat against the fiber bundle rather than becoming upright, thereby preventing entanglement with other fiber bundles while maintaining ease of fiber extraction

AI summary
An optical fiber unit includes: an optical fiber bundle formed by bundling a plurality of optical fibers; and a plurality of bundling members. One bundling member of the plurality of bundling members is wound on an outer circumference of the optical fiber bundle in a length direction of the optical fiber bundle, while reversing a winding direction alternately, and is joined to another bundling member at a section where the winding direction is reversed. A ratio of a width of a cross-section of the bundling member to a thickness of the cross-section of the bundling member is smaller than 20.
