Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fiber optic cabling systems face challenges in efficiently transitioning and maintaining correct polarity, especially when incorporating components from different standards, leading to potential incorrect polarity and reduced bandwidth due to inactive optical paths.
Innovation Solution
The use of multi-fiber optical cables and connectors, such as MTP/MPO connectors, with specific configurations like 12-fiber/path and 24-fiber/path arrangements, ensures active optical paths across all connectors, eliminating inactive paths and allowing for increased bandwidth by optimizing fiber installation and connector configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fiber optic cabling methods (A, B, or C) are used to maintain correct polarity, then polarity correctness is improved, but bandwidth utilization deteriorates due to inactive optical paths
Solution Approach 1:
The invention segments the fiber optic cable into multiple independent pathways, with each pathway capable of carrying separate data streams. By dividing the 12-fiber cable into multiple active pathways rather than using conventional methods that leave paths inactive, all segments can simultaneously transmit data, maximizing bandwidth utilization while maintaining polarity correctness through defined transmit/receive pairings.
Solution Approach 2:
The invention transitions from conventional two-dimensional connector arrangements to a three-dimensional spatial optimization within the 12-fiber cable. By reconfiguring how fibers are routed and terminated across multiple connectors in space, all 12 pathways can be actively utilized rather than leaving some inactive, thereby increasing bandwidth while maintaining polarity through proper dimensional arrangement of transmit and receive paths.
2Productivity
If multi-fiber optical connectors with all active paths are used, then bandwidth utilization is improved, but device complexity increases due to non-standard configurations
Solution Approach 1:
The invention creates a universal connector configuration that can be used across multiple cable assemblies and system implementations. By establishing a standardized method for configuring multi-fiber connectors with all active paths, the solution eliminates the need for custom non-standard connectors while maximizing bandwidth. This universal approach simplifies deployment across different systems rather than increasing complexity.
Solution Approach 2:
The invention changes the configuration parameters of the connector assembly to optimize bandwidth utilization. By modifying how fibers are terminated and routed within standard connectors—specifically configuring 12-fiber cables with all paths active rather than leaving some inactive—the system achieves maximum bandwidth without requiring non-standard connector hardware, thus avoiding increased device complexity.
3Adaptability or versatility
If system evolution incorporates components from different standards, then adaptability is improved, but polarity correctness deteriorates leading to incorrect polarity
Solution Approach 1:
The invention establishes preliminary polarity assignments for each fiber pathway within the 12-fiber cable configuration. By pre-defining which pathways are transmit and which are receive before system deployment, the solution ensures polarity correctness is built into the physical layer. This preliminary configuration allows systems to evolve and incorporate different standards while maintaining correct polarity through the established physical pathway definitions.
Solution Approach 2:
The invention introduces a standardized intermediary configuration layer between different fiber optic standards. The 12-fiber cable with all active paths serves as an intermediary that can interface with various connector types and system configurations while maintaining consistent polarity relationships. This intermediary approach allows system evolution and integration of different standards without compromising polarity correctness.
