Modular Fiber Termination Enclosure for Variable Cable Lengths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic enclosures lack flexibility in accommodating varying fiber optic cable lengths and customized interior components to efficiently distribute fiber optic services across different subscriber types and locations, such as multiple dwelling units, cell towers, and rural areas.
Innovation Solution
A modular fiber optic enclosure assembly with interchangeable modular plate assemblies, including termination adapter arrangements, splice trays, and cable spool arrangements, which can be selectively mounted to customize the enclosure for specific needs, allowing for efficient cable payout and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed configuration fiber optic enclosure is used, then the enclosure structure is simple and easy to manufacture, but it lacks flexibility in accommodating varying fiber optic cable lengths and customized interior components
Solution Approach 1:
The enclosure is divided into modular components including removable plates, splice trays, and cable management assemblies that can be independently configured and replaced. This segmentation allows the enclosure to be customized for different fiber lengths and distribution requirements without redesigning the entire structure.
Solution Approach 2:
The enclosure incorporates dynamic elements such as rotatable cable spools, movable splice trays, and adjustable cable guides that can be repositioned based on installation requirements. These dynamic components enable the enclosure to adapt to varying cable lengths and routing needs while maintaining a relatively simple base structure.
2Adaptability or versatility
If a fixed configuration fiber optic enclosure is used, then the manufacturing process is simple, but it cannot be efficiently customized for different subscriber types and locations
Solution Approach 1:
The enclosure uses standardized modular components that can be manufactured independently using simple processes, then assembled in various configurations. This allows mass production of individual modules with simple manufacturing techniques while enabling complex customized assemblies through modular combination.
Solution Approach 2:
The modular components are designed with universal mounting interfaces and standardized dimensions that allow the same basic parts to serve multiple functions and be used across different enclosure configurations for various subscriber types and locations, simplifying the manufacturing of individual components.
3Adaptability or versatility
If modular plate assemblies are introduced to customize the enclosure, then system design flexibility is enhanced, but the device complexity increases
Solution Approach 1:
The modular plate assemblies are segmented into functional units (termination plates, splice trays, cable guides) that can be independently selected and combined. This segmentation provides system design flexibility by allowing only the necessary modules to be installed for each specific application, rather than requiring all possible components.
Solution Approach 2:
Multiple functional elements are merged into integrated modular plates that combine termination, splicing, and cable management functions in single assemblies. This merging reduces the total number of separate components needed while maintaining the flexibility to configure different system designs.

AI summary
Certain types of fiber termination enclosures include an enclosure and at least one of a plurality of plate module mounting assemblies. Example plate module mounting assemblies include a termination panel plate assembly; a splice tray plate assembly; a cable spool plate assembly; and a drop-in plate assembly. Example cable spool plate assemblies include a cable spool arrangement rotationally coupled to a mounting plate, which fixedly mounts within the enclosure housing. A stand-off mount element may be disposed on the front of the cable spool arrangement to rotate in unison with the cable spool arrangement. The stand-off mount element may include one or more termination adapters.
