Fiber Cabling With Raceway Distribution Modules for Direct Rack Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data center cabling systems require complex connections and intervening switch interfaces, leading to inefficiencies and increased costs.
Innovation Solution
A cabling system that optically couples rack-mounted switches and servers using distribution modules mounted to a raceway, eliminating the need for top-of-rack switches by routing cables directly between switch and server cabinets through distribution modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional top-of-rack switches are used to connect servers, then connectivity is achieved, but device complexity and installation cost increase
Solution Approach 1:
The patent removes the top-of-rack switch from the traditional cabling architecture and extracts its connectivity function, implementing direct fiber optic cable connections between servers and the network switch cabinet. This eliminates the intervening switch component and simplifies the overall system structure while maintaining reliable connectivity.
Solution Approach 2:
The patent segments the cabling system into distinct functional zones: server cabinets with integrated transceivers, distribution modules mounted on raceways, and direct fiber optic connections. This segmentation allows for modular installation and easier maintenance while reducing overall system complexity.
2Reliability
If multiple top-of-rack switches are deployed per rack, then server connectivity is ensured, but installation time and cost increase
Solution Approach 1:
The patent implements pre-configured fiber optic cable runs from the network switch cabinet to distribution modules mounted on the raceway above server cabinets before server installation. This preliminary cabling action eliminates the need for on-site switch installation and reduces overall installation time significantly.
Solution Approach 2:
Server cabinets are designed with integrated transceiver components that enable self-connection to the fiber optic network without requiring external top-of-rack switches. The servers can be directly connected to the network through the pre-installed fiber infrastructure, making the system self-sufficient and reducing installation complexity.
3Reliability
If conventional cable routing through switches is used, then connections are established, but cable management difficulty increases
Solution Approach 1:
The patent introduces distribution modules as intermediary components mounted on the raceway, which serve as structured connection points between the fiber optic cables and server transceivers. These modules provide organized cable routing and connection management, eliminating the need for complex cable routing through multiple switch interfaces.

AI summary
A server rack is cabled to obviate the need for top-of-rack switches. Switches and severs are connected through de-mateable connection interfaces at distribution modules disposed along the raceway above the server cabinets. The distribution modules may have externally accessible ports, internally accessible ports, and/or payout spools for the switch cables and/or the server cables.
