Optical Fiber Termination Cabinet With Identified Holders and Splice Box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cabinets for optical fibers lack an intuitive and secure system for organizing and identifying fibers, especially for distributing them to end users, and the splicing process is complex and prone to errors.
Innovation Solution
A termination cabinet with a splice box and holders that securely store and identify individual fibers, using markers and a moisture seal to protect against environmental factors, and a foundation structure for orderly fiber guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If optical fibres are distributed to households with increasing numbers of fibres, then data communication capacity is improved, but the complexity of organizing and identifying fibres increases
Solution Approach 1:
The cabinet interior is divided into multiple brackets with individual holders, each dedicated to a specific optical fibre. This segmentation allows large numbers of fibres to be organized in a modular fashion, with each fibre having its own designated space, making identification and management straightforward despite the increasing total number of fibres.
2Adaptability or versatility
If fibres are spliced at intervals to extend their length, then fibre distribution coverage is improved, but the vulnerability and complexity of splice maintenance increases
Solution Approach 1:
The cabinet is designed with a dedicated splice box that is prepared in advance to receive and secure spliced fibres. The splice box includes coiling guides and fixation mechanisms that are pre-configured to properly manage the surplus fibre length and maintain the splice in a protected, tension-free state, thereby reducing vulnerability before the splice even needs to be made.
Solution Approach 2:
The splice box acts as an intermediary component between the fibre splicing process and the final fibre installation. It provides a dedicated space where spliced fibres can be temporarily stored and secured, allowing the splice to be protected from environmental factors and mechanical stress while the fibre routing is completed.
3Ease of operation
If fibres are stored in open cabinets for easy access, then ease of operation is improved, but protection against environmental factors deteriorates
Solution Approach 1:
The cabinet is divided into multiple compartments including a dedicated splice box, allowing different fibre management functions to be separated. This segmentation enables secure storage of spliced fibres in the protected splice box while maintaining easy access to individual fibres through the bracket and holder system for routing and connection operations.

AI summary
A termination cabinet (10) for organizing and protecting optical fibres, where a bundle comprising a plurality of optical fibres where each fibre is arranged in a sheeting pipe is introduced into the termination cabinet (10) through a first entrance opening, where a second plurality of optical fibres leading to discreet users in the vicinity of the cabinet, is introduced into the cabinet through a second entrance opening, where each of said fibres from said first plurality of fibres is spliced to a dedicated fibre of the second plurality of fibres, where a length of the spliced fibres is stored in a splice box (20) arranged inside the cabinet, and where one or more holding racks are provided inside said cabinet, where each holding rack has a plurality of holders (12), which holder accommodates and is provided with an unique identifier for the particular single designated fibre.
