Outdoor Fiber Distribution Cabinet Modular Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor fiber optic distribution systems, particularly in US-based PON systems, face challenges with proprietary splitters and fixed internal cabling, making them difficult to service and maintain.
Innovation Solution
An exterior fiber distribution cabinet with modular design, featuring a pivotally mounted module support frame, optical splitter modules, and removable connector holders, allowing for easy access and configuration, and the ability to store excess optical fibers, facilitating efficient connection and disconnection of services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary splitters and fixed internal cabling are used in outdoor fiber distribution cabinets, then the cabinet meets service provider network requirements, but the cabinet becomes difficult to service and maintain
Solution Approach 1:
The cabinet is divided into modular components including removable splitter modules, independent connector holders, and separable mounting frames. Each module can be accessed, removed, or replaced independently without affecting the entire system, enabling easy maintenance while maintaining network reliability through standardized interfaces
Solution Approach 2:
The internal cabling system is transformed from fixed to dynamic through the use of movable connector holders and flexible fiber routing. The connector holders can be removed and repositioned, and the fiber optic cables are routed to allow movement, enabling service personnel to access and reconfigure connections easily while maintaining stable signal transmission
2Ease of operation
If modular design with pivotally mounted support frames is used, then accessibility and ease of service are improved, but device complexity increases
Solution Approach 1:
The support structure is segmented into a pivo tally mounted frame that can rotate to expose different sections of the cabinet interior. This allows service personnel to access components systematically by rotating the frame to positioned needed modules in front of them, improving accessibility without requiring complete disassembly
Solution Approach 2:
The pivo tally frame serves multiple functions: it supports various types of modules (splitters, connectors, adapters), provides structured access to all components, and enables systematic organization of fiber optic cables. This multi-functionality reduces the need for separate access mechanisms for different components, managing complexity through consolidation
