Optic Fiber Cable Fanout Conduit Arrangement Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fanout conduit arrangements for fiber optic cables face challenges in ease of assembly, proper fiber alignment, and securing fibers during and after assembly, as well as protecting fibers from bunching and tangling.
Innovation Solution
A cable fanout conduit arrangement comprising a cable fanout assembly with a cable fanout member and an endcap arrangement, featuring an inspection aperture for access and fixation, and flexible furcation tubes for organizing and securing fibers, which reduces fiber bunching and tangling by channeling fibers into organized substructures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fanout conduit arrangements are used, then fiber management is achieved, but assembly complexity increases and fiber alignment becomes difficult
Solution Approach 1:
The fanout conduit arrangement is divided into modular components including a conduit body, endcaps, and individual fiber channels. This segmentation allows each component to be assembled independently and simplifies the overall assembly process while maintaining organization of multiple fibers.
Solution Approach 2:
Fibers are pre-positioned and aligned within the conduit structure before final securing. The conduit is designed with pre-formed channels and positioning features that guide fibers into correct alignment during assembly, eliminating the need for complex post-assembly alignment procedures.
2Stability of the object's composition
If fibers are fanned out for management, then fiber organization is improved, but fibers become vulnerable to bunching and tangling
Solution Approach 1:
Individual fiber channels are nested within the larger conduit structure, with each channel providing a dedicated pathway for a specific fiber. This nested arrangement maintains fiber separation and organization while protecting against bunching and tangling, as fibers remain confined to their respective channels throughout the fanout arrangement.
Solution Approach 2:
The conduit structure acts as an intermediary between the bundled cable and the fanned-out fibers. It provides a controlled environment with individual channels that mediate the transition from bundled to separated state, preventing direct interaction between fibers that would cause tangling while maintaining organized separation.
3Ease of repair
If inspection access is provided for fiber examination, then maintenance capability is improved, but conduit structure complexity increases
Solution Approach 1:
Endcaps are designed with removable or open sections that allow extraction of fibers for inspection and maintenance. This extraction capability provides direct access to fibers at both ends of the conduit without requiring disassembly of the entire conduit structure, simplifying maintenance while adding minimal structural complexity through the endcap design.
