Fiber Distribution Hub Segmented Enclosure Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fiber optic network distribution points require a solution that allows for efficient maintenance and replacement of components without disrupting the entire system, as existing interconnect cabinets are cumbersome and costly to service.
Innovation Solution
A fiber distribution hub with a releasably coupled splice enclosure and patch enclosure, enabling independent access and replacement of components, such as the splice enclosure, while maintaining a weather-tight seal to protect against environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a traditional interconnect cabinet is used to enclose all fiber distribution components, then all components are protected together, but maintenance and replacement of individual components require disrupting the entire system and incur high costs
Solution Approach 1:
The fiber distribution hub is divided into separate enclosures: a splice enclosure containing splice connections and a patch enclosure containing termination points and mounting plates. This segmentation allows independent access and maintenance of each enclosure without disrupting the entire system, resolving the contradiction between ease of repair and device complexity.
2Reliability
If a large rectangular concrete foundation is used to support the interconnect cabinet, then the system is stable and protected, but installation and servicing are cumbersome and costly
Solution Approach 1:
The fiber distribution hub uses a modular design with separate splice and patch enclosures that can be mounted on smaller, simpler foundations such as concrete pads or wall-mounted brackets. This segmentation reduces the size and complexity of the foundation structure while maintaining system stability, making installation and servicing easier and more cost-effective.
3Adaptability or versatility
If the splice enclosure is permanently integrated with the patch enclosure, then the structure is simpler, but damaged components cannot be replaced independently
Solution Approach 1:
The splice enclosure and patch enclosure are connected through a releasable coupling mechanism that allows them to be separated and reconnected. This dynamic coupling enables independent replacement and maintenance of each enclosure while maintaining a relatively simple overall structure, resolving the contradiction between adaptability and device complexity.

AI summary
Fiber distribution hubs for distributing fiber optic networks are disclosed. The fiber distribution hub includes a mounting plate for supporting a termination of at least one fiber cable, a patch enclosure for protecting the termination, and a splice enclosure for protecting at least one splice connection to an optical fiber included in a feeder cable. The patch enclosure includes a first door and defining a patch chamber. The mounting plate is positioned within the patch chamber. The splice chamber includes a second door. The splice enclosure is releasably coupled to the patch enclosure.
