Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of optical networks is hindered by the need for skilled labor and time-consuming splicing methods, and the increased connectivity requirements in datacenters due to AI deployments lead to space constraints and limited fiber optic connectivity in equipment racks.
Innovation Solution
A system and method for high-density fiber optic cable routing using a rack with fiber distribution units (FDUs) that align fiber ports with fiber connection adapters in a 1:1 ratio, allowing for efficient alignment and orthogonal connection of fiber jumpers, accommodating ultra-high fiber counts, and reducing cable bulk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If additional computing equipment is added to racks to accommodate AI connectivity requirements, then fiber count requirements increase, but rack space becomes limited and cable bulk increases
Solution Approach 1:
The patent transitions from traditional horizontal cable routing to vertical cable routing by positioning fiber distribution units along the vertical sidewalls of the rack. This dimensional change allows cables to enter and exit the rack vertically, utilizing the unused vertical space and preventing cable bulk from occupying valuable horizontal rack volume, thereby accommodating higher fiber counts without compromising rack space
Solution Approach 2:
The patent introduces fiber distribution units as intermediary devices positioned outside the main rack interior, along the sidewalls. These units serve as mediators that organize and manage high-density fiber connections, allowing multiple fiber cables to be routed efficiently through dedicated vertical pathways rather than cluttering the rack interior, thus enabling increased fiber count while preserving rack space
2Area of stationary object
If fiber distribution units are positioned outside the rack interior along sidewalls, then rack space is preserved, but cable routing complexity increases
Solution Approach 1:
The patent segments the cable routing function by separating it from the main rack interior and placing fiber distribution units along the sidewalls. This segmentation creates dedicated vertical zones for cable management, simplifying the routing path for each cable group and reducing the overall complexity of managing high-density fiber connections within the rack
3Reliability
If traditional splicing methods are used for optical network deployment, then connection reliability is achieved, but deployment time increases
Solution Approach 1:
The patent implements preliminary action by pre-organizing and pre-positioning fiber distribution units with their connection adapters ready before actual network deployment. The vertical routing structure and pre-configured adapter positions allow for rapid connection establishment, eliminating time-consuming field splicing operations while maintaining connection reliability through factory-prepared interfaces
