Cable Retainer Box Layout for Fiber-Safe Cabinet Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable management systems in central switching offices often disturb the orientation of optical fiber cables during new cable installations, leading to increased signal attenuation, as they require lashing with existing cables, which is not efficient for both optical fiber and data copper cables.
Innovation Solution
The implementation of separate cable retainer boxes (CRBs) for data copper and optical fiber cables within a cabinet, with distinct openings and edge guards to facilitate efficient routing and installation, reducing friction and signal interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If new cables are lashed to existing cables for support, then new cables gain adequate support, but existing cable orientation is disturbed and signal attenuation increases
Solution Approach 1:
The patent introduces separate cable management structures for different cable types (optical fiber and data copper) rather than mixing them. Each cable type has its own dedicated routing path and support structure, preventing interference between cables and eliminating the need to lash new cables to existing ones.
Solution Approach 2:
The patent employs intermediate support structures such as cable retainers, guides, and dedicated mounting locations within the cabinet that provide support for new cables without requiring attachment to existing cables. These intermediary elements act as mediators that fulfill the support function while preserving existing cable integrity.
2Reliability
If separate cable management structures are provided for different cable types, then cable organization and signal quality improve, but device complexity increases
Solution Approach 1:
The patent designs universal cable management components that can accommodate multiple cable types and configurations. The cabinet structure includes standardized mounting locations, retainers, and guides that serve multiple functions - supporting both optical fiber and data copper cables with the same basic structural elements, thereby reducing overall complexity.
Solution Approach 2:
The patent combines cable management functions into integrated cabinet structures where support, routing, and organization features are merged into unified components. Rather than separate systems for each cable type, the design merges multiple cable management requirements into a coordinated structural framework.
Data Source
AI summary
A cable management cabinet is improved by separately managing the routing of data copper cables and optical fiber cables within the cabinet. This is accomplished by providing separate cable retaining boxes (CRBs) for data copper cables and optical fiber cables respectively. The CRBs are provided with front openings to facilitate installation and routing of optical fiber cables and data copper cables. The openings may be provided with edge guards to ease ingress/egress of cables through the openings.
