Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-density optical fiber cabling, the tight bundling of fibers makes it difficult to efficiently identify or tag optical fibers, as written labels are impractical and wireless identification methods are hindered by the close spacing, leading to challenges in troubleshooting and managing connectivity within confined spaces.
Innovation Solution
An electronically-managed optical fiber connection system using tagged optical ferrule assemblies, smart ferrule carriers, and smart adapters that include identification tags and controllers to automatically detect and read identification information, enabling efficient management and debugging of optical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If optical fibers are tightly bundled to achieve high-density connectivity, then the number of connections per unit space increases, but the ability to identify and tag individual fibers deteriorates
Solution Approach 1:
The patent implements nesting by placing identification tags inside the adapter housing, which itself is nested within the optical connection system. The controller is embedded within the adapter, and tags are integrated into ferrules or carrier components. This nested arrangement allows identification functionality to be incorporated without increasing the external footprint of the fiber bundle, thereby maintaining high density while enabling identification.
Solution Approach 2:
The patent transitions from two-dimensional surface labeling (which becomes impossible in tight bundles) to three-dimensional spatial arrangement of identification components. Tags are positioned at multiple locations within the adapter housing and on different components (ferrules, carriers), allowing identification through spatial relationships rather than surface labels. The system uses dimensional positioning of tags and optical pathways to identify fibers without requiring external surface space.
2Ease of operation
If wireless identification methods are used for optical fibers, then identification capability is improved, but the close spacing of fibers in high-density bundles causes interference and reduces effectiveness
Solution Approach 1:
The patent introduces an intermediary controller that mediates between the identification tags and the external identification system. The controller reads tags through optical pathways within the adapter housing, acting as an intermediary that eliminates the need for direct wireless communication between externally placed readers and fiber tags. This intermediary approach avoids interference from close fiber spacing while maintaining identification capability.
Solution Approach 2:
The patent replaces wireless electromagnetic field-based identification with an optical mechanism where the controller reads tags through optical pathways. This substitution of the identification mechanism from wireless electromagnetic fields to optical reading through structured pathways eliminates interference issues associated with close fiber spacing, as the optical pathways are contained within the adapter housing and do not radiate externally.
3Ease of manufacture
If traditional labeling methods are used on optical fibers, then identification is simple, but the labels become illegible or inaccessible in high-density configurations
Solution Approach 1:
The patent extracts the identification function from the fiber surface itself and places it in separate, accessible locations within the adapter housing. Tags are positioned on ferrules, carriers, or the adapter housing interior, separate from the tightly bundled fiber surfaces. This extraction allows identification information to be accessed through the adapter interface rather than requiring access to the inaccessible fiber surfaces in high-density bundles.
Solution Approach 2:
The patent creates multiple copies of identification information through redundant tag placement. Tags are positioned on multiple components (ferrules, carriers, adapter housing) and can be read through multiple optical pathways. This redundancy ensures that identification information remains accessible even if one pathway is blocked, and provides backup identification methods without requiring external label access.
