Fiber Optic Crossover Cable Switch Interconnect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fiber optic adapter cabinets for data center switches experience high connection loss and require numerous components, leading to increased costs and inefficiencies in signal transmission between switches.
Innovation Solution
A fiber optic crossover cable design that uses a crossover distribution unit to bundle and rearrange fiber optic subunits between two switch groups, eliminating the need for multiple backplanes and reducing the number of connectors required, thereby minimizing connection loss and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional adapter cabinets with multiple backplanes and fiber connectors are used to connect switches, then communication between switches is enabled, but connection loss increases and component quantity increases leading to higher cost
Solution Approach 1:
The patent combines multiple fiber optic subunits into a single bundled cable assembly that directly connects switch groups, eliminating the need for separate backplanes and individual fiber connectors. This merging approach reduces the total number of components while maintaining reliable signal transmission between switches.
Solution Approach 2:
The fiber optic crossover cable is designed to perform multiple functions: it provides signal transmission, physical protection through bundling, and direct connection between switch groups. This multi-functional design replaces the need for separate connection components, reducing overall system complexity while maintaining transmission quality.
2Productivity
If traditional adapter cabinets with multiple backplanes and fiber connectors are used to connect switches, then communication between switches is enabled, but connection loss increases
Solution Approach 1:
By bundling multiple fiber optic subunits into a single integrated cable assembly, the patent minimizes the number of connection points and interfaces. This reduces signal loss at connectors and backplanes, improving overall signal transmission efficiency between switch groups.
3Ease of operation
If multiple backplanes and fiber connectors are used in adapter cabinets, then switch communication is established, but cost increases due to numerous components
Solution Approach 1:
The patent merges multiple fiber optic connections into a single bundled cable assembly that can be installed as one unit between switch groups. This eliminates the need to individually connect multiple backplanes and fiber connectors, significantly simplifying installation while reducing the total component count.
