Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical fiber connectors face alignment issues leading to signal degradation and mechanical failure due to insufficient resistance to pull-off forces, as conventional assemblies fail to adequately secure the fiber optic cables.

A fiber optic connector assembly featuring a crimp body with a fiber access aperture and a crimp band that securely attaches the optical fiber ribbon to the connector, utilizing a crimp band and crimp body design to enhance alignment and mechanical interlock, thereby preventing signal attenuation and cable breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional cable assemblies are used, then the structure is simple, but the resistance to cable pull-off forces is insufficient
Solution Approach 1:
The cable assembly is divided into distinct functional segments: a crimp body for structural support, a crimp band for mechanical attachment, and a fiber access aperture for alignment. This segmentation allows each component to be optimized for its specific function while working together to provide superior pull-off resistance.
Solution Approach 2:
The fiber access aperture introduces a new dimensional aspect to the connector design, providing a lateral access path for fiber alignment and insertion. This dimensional addition enables improved mechanical interlocking without increasing the overall footprint of the connector in the primary transmission direction.
2Manufacturing precision
If conventional alignment methods are used, then the assembly process is simple, but optical fiber alignment precision is insufficient leading to signal degradation
Solution Approach 1:
The crimp body and crimp band are pre-configured with alignment features and geometric constraints that guide the optical fiber into the correct position during assembly. This preliminary structuring of alignment capabilities eliminates the need for complex real-time adjustment mechanisms, maintaining high assembly efficiency while achieving precise fiber alignment.
Solution Approach 2:
The fiber access aperture and crimp structure are designed to self-align the optical fiber through geometric constraints and mechanical interference fits. The structure itself provides the alignment function without requiring external alignment tools or complex adjustment procedures, thereby maintaining productivity while improving precision.

AI summary
A fiber optic connector assembly includes a fiber optic cable with one or more optical fiber ribbons attached to a fiber optic connector. The connector includes a ferrule assembly and a crimp body with a fiber access aperture. The aperture has at least two walls defining a first width and a second width defining a predetermined delta and a predetermined aspect ratio. The delta and aspect ratio provide optical fiber access for alignment of the optical fiber ribbon to the optical fiber ferrule assembly. A method of making the fiber optic connector assembly is also disclosed.
