Solution Overview

Problem

The complexity and cost of physically connecting a large number of cables in high-density network environments, such as large-scale supercomputers or datacenters, are exacerbated by the need for precise wiring and the potential for human error, especially in multi-fiber cable networks with complex topologies like all-to-all, HyperX, and Dragonfly.

Innovation Solution

Implementing a single-stage shuffle box solution using multi-fiber cables (MFCs) and shuffle boxes, such as connected and bipartite shuffle boxes, to reduce the number of shuffle boxes and fiber length, thereby reducing signal loss and power consumption, while maintaining connectivity across nodes or switches.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If traditional individual fiber connections are used, then connectivity between devices is established, but the number of cables and wiring complexity increases significantly

Engineering Contradiction:
Improvewiring complexityVSAvoidnumber of cables
Core Design Contradiction:
Device complexityVSQuantity of substance

Solution Approach 1:

Multiple individual fiber connections are merged into a single multi-fiber cable assembly. The patent combines multiple fibers (e.g., 8, 16, or more fibers) into one bundled cable that connects to multiple ports simultaneously, reducing the total number of separate cable connections required while maintaining all necessary connectivity paths between network devices.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If more shuffle boxes are used to manage fiber connections, then connectivity flexibility is improved, but signal loss and power consumption increase

Engineering Contradiction:
Improveconnectivity flexibilityVSAvoidsignal loss
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent extracts and eliminates intermediate shuffle boxes from the fiber connection path by implementing direct multi-fiber cable connections between network devices. This removes unnecessary signal transmission stages, reducing signal loss and power consumption while maintaining connectivity flexibility through the multi-fiber cable's inherent ability to support multiple connection patterns.

Inventive Principle:
Principle #2Taking out (Extraction)

3Area of stationary object

If individual fiber connections are used, then connection precision is maintained, but the physical footprint and space requirements increase

Engineering Contradiction:
Improvephysical footprintVSAvoidconnection precision
Core Design Contradiction:
Area of stationary objectVSManufacturing precision

Solution Approach 1:

Multiple fiber connections are merged into a single multi-fiber cable assembly with integrated connectors. This consolidation reduces the physical footprint by grouping multiple fibers together in one cable bundle rather than requiring separate cable routes and connector positions for each individual fiber, while maintaining precise connections through standardized multi-fiber connector designs.

Inventive Principle:
Principle #5Merging (Combining)
