Multi-Configuration FDH Mounting Brackets for Pole Offset Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passive optical networks require adaptable fiber distribution hubs (FDHs) that can be configured for various mounting locations and applications, with the need for convenient access and storage of fibers to facilitate reconfiguration and maintenance without increasing network complexity or cost.
Innovation Solution
The implementation of a multi-configuration mounting system for FDHs, including a hinged storage panel that can be mounted on a vertical or horizontal axis, allowing for flexible placement and access, along with rearrangeable mounting brackets to accommodate different pole offsets, enabling technicians to easily reconfigure optical connections based on specific application needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed configuration mounting system is used for FDHs, then the mounting structure is simple and cost-effective, but the system lacks adaptability to different mounting locations and applications
Solution Approach 1:
The mounting bracket is designed with multiple mounting holes arranged in different patterns (e.g., triangular, linear) that can accommodate various pole offsets and mounting configurations. The same bracket can be used for different FDH sizes and mounting locations by selecting different hole combinations, making the mounting system universal and adaptable without requiring multiple specialized brackets.
Solution Approach 2:
The mounting system allows for dynamic reconfiguration through the selective use of different mounting holes and the ability to reposition the FDH on the pole. The bracket can be removed and reinstalled in different configurations, enabling the system to adapt to changing requirements without permanent modifications.
2Ease of operation
If a hinged storage panel is used to improve access to stored fibers, then maintenance and reconfiguration convenience is improved, but the device complexity increases
Solution Approach 1:
The FDH cabinet is divided into functional sections with a hinged storage panel that can be independently opened. This segmentation allows technicians to access stored fibers without opening the entire cabinet or disrupting other components, providing targeted access to specific fiber storage areas while maintaining the integrity of the overall system.
Solution Approach 2:
Fibers are pre-organized and stored in dedicated storage modules behind the hinged panel during installation. This preliminary organization allows for quick retrieval and reconfiguration during maintenance, as fibers are already positioned and ready for connection rather than requiring complex routing during service operations.
3Adaptability or versatility
If multiple mounting hole patterns are provided on the FDH cabinet, then adaptability to different pole offsets is improved, but the manufacturing complexity increases
Solution Approach 1:
The FDH cabinet is equipped with multiple sets of mounting holes arranged in different geometric patterns (e.g., equilateral triangle, isosceles triangle, linear arrangements) that can accommodate various pole offsets. The same cabinet design with these integrated mounting patterns can be used across different installation scenarios, eliminating the need to manufacture multiple specialized cabinet variants.
Solution Approach 2:
The mounting hole patterns provide different geometric parameters (distances, angles, orientations) to accommodate varying pole offsets. By incorporating these multiple parameter configurations into a single cabinet design, the system can adapt to different installation geometries without requiring custom manufacturing for each scenario.

AI summary
A fiber distribution hub (FDH) includes an enclosure and brackets with provisions to be mountable in multiple configurations. More particularly, the FDH is mountable in multiple configurations to a pole. The brackets are rearrangeable to provide the mounting configuration with either a short or extended offset between an FDH cabinet and the pole.
