Solution Overview
Problem
Existing cable technologies face challenges in providing efficient and scalable connectivity for both power and data to remote devices, particularly in radio-over-fiber systems, where accessing and extending connections is cumbersome and requires multiple cables.
Innovation Solution
A micromodule cable design featuring a cable jacket with multiple subunit cables, each containing optical fibers and electrical conductors, allowing for easy access and extension by severing and pulling out subunit cables as 'tether' connections, providing flexible and scalable power and data connectivity to remote devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate cables are used to provide power and data connectivity to remote devices, then reliable power and data transmission is achieved, but cable management becomes cumbersome and installation complexity increases
Solution Approach 1:
The patent combines multiple separate cables (power cable and data cable) into a single integrated micromodule cable. The cable jacket contains both power conductors and optical fibers in close proximity, allowing simultaneous power and data transmission through one cable rather than requiring separate cable routing and management.
Solution Approach 2:
The micromodule cable serves multiple functions simultaneously - it provides both electrical power transmission through conductors and optical data transmission through fibers within the same cable structure. This multi-functional design eliminates the need for separate dedicated power and data cables.
2Strength
If traditional cable structures are used, then structural integrity is maintained, but accessibility to individual conductors and fibers for extension connections is difficult
Solution Approach 1:
The cable structure is segmented into distinct subunit cables, each containing specific conductors or fibers. This segmentation allows individual subunits to be accessed, severed, and extended independently while maintaining the integrity of the overall cable structure. The modular subunit design facilitates easy access to specific components without compromising the main cable.
3Adaptability or versatility
If multiple cables are deployed for power and data, then sufficient connectivity capacity is provided, but installation time and labor requirements increase
Solution Approach 1:
By merging power and data transmission capabilities into a single micromodule cable, the installation process requires handling and routing only one cable instead of multiple separate cables. This reduces installation time and labor while maintaining full connectivity capacity for both power and data to remote devices.

AI summary
Micromodule cables include subunit, tether cables having both electrical conductors and optical fibers. The subunits can be stranded within the micromodule cable jacket so that the subunits can be accessed from the micromodule cable at various axial locations along the cable without using excessive force. Each subunit can include two electrical conductors so that more power can be provided to electrical devices connected to the subunit.
