Segmented Ferrule Boot for Multi-Fiber Optical Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-fiber fiber optic connectors face challenges in effectively protecting loose optical fibers and preventing epoxy resin leakage, particularly when no protective hardware is present, and they often require de-ribbonizing processes that are not necessary for non-ribbonized fibers.
Innovation Solution
A ferrule boot with a body member defining multiple lengthwise openings to receive optical fibers, coupled with a multi-fiber ferrule and a spring mechanism for biasing the ferrule, provides strain relief and bend radius protection, allowing for secure alignment and sealing of optical fibers without the need for de-ribbonizing, and includes a connector boot for additional protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional ferrule boot with a single elongated slot is used, then the structure is simple and easy to manufacture, but it cannot effectively protect loose optical fibers and prevent epoxy resin leakage
Solution Approach 1:
The ferrule boot is divided into multiple segments or sections, each with specific openings positioned at different locations. This segmentation allows the boot to provide targeted protection for loose optical fibers while maintaining structural integrity and preventing epoxy leakage, resolving the contradiction between reliability and complexity.
Solution Approach 2:
Different regions of the ferrule boot are designed with different properties - certain areas have openings for fiber access while other areas provide sealed protection. This local differentiation enables the boot to simultaneously protect loose fibers and prevent epoxy leakage without requiring complete structural redesign.
2Reliability
If a conventional ferrule boot with a single elongated slot is used, then the manufacturing process is simple, but epoxy resin flows out of the connector
Solution Approach 1:
The ferrule boot incorporates multiple sealed compartments or sections with controlled openings, creating barriers that prevent epoxy resin from flowing out while maintaining manufacturing feasibility through modular construction techniques.
Solution Approach 2:
The ferrule boot is designed to perform multiple functions simultaneously - protecting loose fibers, preventing epoxy leakage, and maintaining structural support - all within a single component that can be manufactured using standard processes.
3Manufacturing precision
If de-ribbonizing process is used in conventional connectors, then fiber alignment is achieved, but the process is complex and time-consuming
Solution Approach 1:
The ferrule boot is designed to receive and pre-align optical fibers in their ribbon configuration before final connector assembly. This preliminary action maintains fiber alignment without requiring the time-consuming de-ribbonizing process, thereby improving productivity while preserving manufacturing precision.
Solution Approach 2:
The invention extracts or eliminates the de-ribbonizing step from the conventional assembly process by designing a ferrule boot that can directly accommodate and align fibers in ribbon form, simplifying the manufacturing process while maintaining alignment precision.
4Reliability
If no protective hardware is present, then the connector structure is simpler, but strain relief and bend radius protection are insufficient
Solution Approach 1:
The ferrule boot is designed as a multi-functional component that simultaneously provides strain relief, bend radius protection, and fiber alignment capabilities. By consolidating multiple protective functions into a single component, the invention improves reliability without significantly increasing overall device complexity.
Solution Approach 2:
The ferrule boot incorporates flexible material design that provides strain relief and bend radius protection through its inherent elasticity and conformability, offering protective hardware functionality without requiring rigid, complex structural elements.
