Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies do not provide an optical fiber branching switching apparatus that can effectively branch and switch a multi-core fiber to another multi-core fiber, as they primarily focus on converting multi-core fibers into single fibers through fan-in/fan-out processes without addressing the need for branching and switching between multi-core fibers.
Innovation Solution
The optical fiber branching switching apparatus connects multiple optical fibers with fan-in/fan-out devices to enable branching and switching between multi-core fibers, using various configurations of optical fibers and switching apparatuses to facilitate signal transmission and reception between multiple cores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fan-in/fan-out process is used to convert multi-core fiber to single fiber, then signal transmission between nodes is achieved, but the ability to branch and switch multi-core fiber to multi-core fiber is lost
Solution Approach 1:
The patent divides the fiber connection system into multiple independent core units, where each core can be independently switched between different destination cores. This segmentation allows the system to maintain multi-core fiber connectivity while enabling flexible branching and switching capabilities through individual core control.
Solution Approach 2:
The patent introduces dynamic switching mechanisms that allow the fiber connection configuration to change over time. The system can dynamically reconfigure which cores are connected to which destinations based on traffic demands, enabling the fiber infrastructure to adapt to varying network requirements without physical reconfiguration.
2Productivity
If multi-core fiber is converted to single fiber through fan-in/fan-out, then connection simplicity is improved, but network capacity and parallel transmission capability are reduced
Solution Approach 1:
The patent merges multiple single-mode fibers into a multi-core fiber structure, combining the transmission capabilities of individual fibers while maintaining their independence. This merging approach preserves the parallel transmission capacity of multiple fibers while providing the structural integration and switching flexibility of a multi-core fiber system.
Solution Approach 2:
The patent creates a universal fiber switching structure that can handle multiple functions: it can switch signals between different destination cores, support both short-range and long-range transmissions, and accommodate various traffic patterns. This multi-functional design increases network capacity while using a unified structural approach.
