Fiber Optic Breakout Assembly Double D Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In next-generation wireless communication systems, the separation of remote radio units from baseband controllers over long distances using fiber optic cables poses challenges in managing individual fiber connections efficiently, often requiring a single large multi-fiber optic cable to serve multiple RRUs, which can be cumbersome and prone to mechanical stress.
Innovation Solution
A breakout assembly is used to separate optical fibers from a multi-fiber optic cable into individual pairs, utilizing a clear transparent plastic housing with epoxy encapsulation to protect and secure the fibers, and a double D design to prevent microbending and twisting, along with a weather-resistant enclosure to facilitate easy installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single large multi-fiber optic cable is used to operate individual RRUs, then the number of cables is reduced, but the cable becomes cumbersome and prone to mechanical stress
Solution Approach 1:
The patent divides the multi-fiber optic cable into multiple individual fiber pairs, each housed in separate protective conduits within a breakout assembly. This segmentation allows each fiber to be independently managed and protected, reducing mechanical stress on the entire cable system while maintaining the reduced cable quantity benefit.
2Ease of operation
If a breakout assembly is used to separate optical fibers into individual pairs, then fiber management is improved, but the assembly complexity increases
Solution Approach 1:
The patent combines multiple individual fiber pairs into a single integrated breakout assembly housing with unified encapsulation. This merging approach simplifies the overall structure by consolidating what could be multiple separate components into one assembly, making installation and maintenance easier while still providing individual fiber management capabilities.
Solution Approach 2:
The patent uses epoxy encapsulation material that combines protective, structural, and organizational functions. This composite material approach simplifies the assembly structure by using a single material system that provides mechanical protection, fiber stabilization, and environmental sealing, rather than requiring multiple separate protective components.
3Reliability
If epoxy encapsulation is used to encase parts within the housing, then fiber protection is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent positions and secures all fiber pairs and components within the housing before applying the epoxy encapsulation. This preliminary arrangement ensures proper fiber alignment and protection is established prior to encapsulation, allowing the epoxy to be applied as a single protective layer rather than requiring complex post-encapsulation adjustments.
4Object-affected harmful factors
If a weather-resistant enclosure is used to protect the breakout assembly, then environmental protection is improved, but the installation complexity increases
Solution Approach 1:
The patent integrates the weather-resistant enclosure features directly into the breakout assembly housing design, combining environmental protection functionality with the structural housing. This merging eliminates the need for separate external protective enclosures, reducing installation complexity while maintaining environmental resistance.

AI summary
A breakout assembly includes a housing including a first end and a second end. A retaining member includes a first end configured to receive a fiber optic cable and a second end attaching to the first end of the housing and retaining exposed stripped layers of the fiber optic cable. A breakout head is configured to insert into the second end of the housing and includes holes for receiving furcation tubes. A nut holds the breakout head inside of the second end of the housing. Different optical fibers from the fiber optic cable are inserted into the furcation tubes and held by the breakout head. An outside surface of the breakout head and an inside surface of the second end of the housing have round side surfaces extending between flat top and bottom surfaces that prevent the breakout head from rotating within the housing.
