Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing and terminating hybrid cables that include both optical fibers and electrical conductors poses unique challenges due to the differences in how these components should be handled and connected, with existing solutions failing to provide effective separation and protection.
Innovation Solution
The development of enclosures that include a management insert with multiple levels for separating and managing optical fibers and electrical conductors, featuring a deck with a stable platform for power termination, fiber optic connection, and fiber management, secured within a housing like a NEMA-rated box, and dedicated furcation enclosures for separating transmission lines without additional termination functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hybrid cable termination uses a single-level enclosure, then device complexity is reduced, but optical fibers and electrical conductors cannot be effectively separated and protected during termination
Solution Approach 1:
The enclosure is divided into multiple levels (first level for cable entrance and separation, second level for electrical conductor termination, third level for optical fiber termination and storage). This segmentation allows effective separation and protection of different media types while providing dedicated spaces for each termination process, resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The patent transitions from a single-level (2D) enclosure to a multi-level (3D) structure. By utilizing vertical space and creating distinct levels within the enclosure, the design enables simultaneous separation and protection of optical fibers and electrical conductors without significantly increasing the enclosure's footprint, thus improving reliability while controlling complexity.
2Ease of operation
If optical fibers and electrical conductors are handled together in the same space, then ease of operation is improved, but protection of optical fibers during electrical conductor termination is compromised
Solution Approach 1:
The enclosure separates optical fiber handling and electrical conductor termination into different levels (third level for optical fibers, second level for electrical conductors). This segmentation provides ease of operation by organizing components logically while simultaneously protecting optical fibers from damage during electrical conductor termination activities.
Solution Approach 2:
The patent introduces intermediate structures such as the first level as a transition zone between cable entrance and termination points, and uses physical barriers and designated pathways to mediate between optical fibers and electrical conductors. These intermediaries facilitate easy access while preventing harmful interactions between the two media types.
3Adaptability or versatility
If a dedicated furcation enclosure is used without termination functionality, then adaptability for different installation scenarios is improved, but productivity of cable termination process is reduced
Solution Approach 1:
The enclosure is designed with multi-functionality to resolve the contradiction between adaptability and productivity. It provides dedicated furcation capability with multiple mounting options (wall, rack, cable trough) while simultaneously integrating termination functionality at multiple levels. The universal design allows the same enclosure to serve both as a furcation device and a termination enclosure, eliminating the need for separate devices and improving overall process efficiency.

AI summary
An enclosure includes a management insert disposed within a housing to divide the interior into three levels. Hybrid cables enter the housing at the first level. Electrical conductors of the hybrid cables are terminated at the second level. Optical fibers of the hybrid cables are terminated at the third level. Excess length of the optical fibers may be stored at the third level. The management insert may be fastened to the housing using plugs received at select ones of the cable entrance/exit locations. A dedicated furcation enclosure is also disclosed.
