Hybrid Fiber Patch Cable Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fiber terminals often require different optical fiber connection formats when service providers change, necessitating the installation of new drop cables with matching connectors, which is inefficient and labor-intensive.
Innovation Solution
A fiber patch cable assembly with a male connector of one format on one end and a sealed connector receiver of a different format on the other end, allowing adaptation between various connector formats at the terminal and drop cable interface, while providing an environmental seal to protect the enclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fiber terminal uses a specific optical connector format, then reliable optical connection is achieved, but adaptability to different service providers and connector formats is reduced
Solution Approach 1:
The patent introduces a patch cable assembly as an intermediary component between the fiber terminal and the service provider's drop cable. The patch cable has a connector on one end that interfaces with the terminal and a receptacle on the other end that accepts different service provider connectors. This intermediary device enables format adaptation without modifying the terminal itself, resolving the contradiction between maintaining reliable connections and adapting to different formats.
Solution Approach 2:
The patch cable assembly is designed with universal functionality to support multiple connector formats through its receptacle interface. The receptacle can accommodate various service provider connectors while maintaining a consistent interface with the terminal. This multi-functionality allows a single terminal installation to work with different service providers using different connector standards.
2Adaptability or versatility
If new drop cables are installed to change connector formats, then connector format compatibility is improved, but installation complexity and labor intensity increase
Solution Approach 1:
The system is segmented into three distinct components: the fiber terminal, the patch cable assembly, and the service provider's drop cable. This segmentation allows the format adaptation function to be isolated in the patch cable, which can be easily replaced or reconfigured without affecting the terminal or the drop cable. Installation becomes simpler as technicians only need to connect pre-assembled components rather than install entirely new cables.
3Ease of operation
If conventional optical connectors are used without environmental sealing, then ease of installation is maintained, but protection against environmental ingress is reduced
Solution Approach 1:
The patent merges the environmental sealing function with the optical connector interface by integrating a seal around the connector where it enters the terminal housing. This combined design provides both connection functionality and environmental protection without requiring separate sealing components or complex installation procedures. The seal is incorporated into the connector assembly itself, maintaining ease of installation while protecting against environmental factors.
