Ribbon Fiber Optical Interconnect for WDM Signal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing data rates and rapid deployment of WDM technology lead to a dramatic increase in the number of optical signals that need to be interconnected, resulting in an explosive use of fibers, which complicates fiber management, system maintenance, reliability assurance, and troubleshooting in optical signal transportation systems.
Innovation Solution
The use of a compact optical interconnect apparatus that includes a first and second set of ribbon fibers attached to WDM filters, with the first set connected through an MPO/MTP connector and the second set connected via a fan-out kit to individual fiber cables, forming a single continuous optical signal path that reduces the number of individual fibers needed for interconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple individual fibers are used to interconnect optical signals between bays, then the number of optical signals that can be transmitted increases, but the complexity of fiber management and system maintenance increases dramatically
Solution Approach 1:
Multiple individual fiber connections are merged into a single ribbon fiber assembly. The patent shows that 12-24 individual fibers that would traditionally require separate management are combined into one organized ribbon structure with a single connector housing, reducing the number of separate fiber cables from dozens to just one manageable unit.
Solution Approach 2:
The fiber assembly is segmented into functional groups within the ribbon structure. Individual fibers are organized into specific positions within the ribbon (e.g., 12 or 24 positions) that correspond to specific optical signals or wavelength channels, allowing systematic management while maintaining the consolidated ribbon format.
2Productivity
If the number of fibers is increased to support WDM technology, then data transmission capacity increases, but the space required for fiber routing and management increases
Solution Approach 1:
Multiple fiber routing paths are merged into a single ribbon fiber assembly that occupies minimal space. The compact ribbon structure with integrated connector housing reduces the physical footprint required for fiber routing from what would be dozens of separate cable paths to a single organized bundle.
Solution Approach 2:
The fiber arrangement transitions from a three-dimensional scattered routing of individual cables to a planar two-dimensional ribbon structure. This dimensional change allows multiple fibers to be organized in a flat, compact arrangement that requires significantly less routing space while maintaining all necessary connections.
3Adaptability or versatility
If individual fiber cables are used for each optical signal, then connection flexibility is maintained, but troubleshooting and maintenance difficulty increases
Solution Approach 1:
While maintaining the flexible ribbon structure, each individual fiber within the ribbon is assigned to a specific optical signal or wavelength channel. This segmentation allows technicians to identify and troubleshoot specific fibers by their position in the ribbon corresponding to their function, making maintenance as easy as with individual cables but with the organizational benefits of the ribbon format.
