Solution Overview
Problem
Conventional cellular tower sites face challenges with limited space for fiber optic breakout assemblies and are susceptible to damage from overvoltage and surge currents, requiring additional power and fiber cabling which increases energy loss and costs.
Innovation Solution
A compact hybrid distribution unit that integrates power and data connections within a single enclosure, providing overvoltage protection and reducing the overall footprint on the tower, while allowing for efficient routing and protection of cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If processing units are located near the antenna at the top of the tower, then energy loss via RF cable is minimized, but additional power and fiber optic cabling is required and the unit is susceptible to damage from overvoltage and surge current
Solution Approach 1:
A hybrid cable assembly serves as an intermediary component that combines fiber optic cables and power cables into a single integrated unit. This mediator distributes both data and power connections from a common enclosure to multiple radio units, reducing the need for separate cabling while providing centralized overvoltage protection through integrated suppressors at the distribution point
Solution Approach 2:
The patent combines multiple functions into a single hybrid cable assembly: data transmission via fiber optic cables, power distribution through copper conductors, and overvoltage protection via integrated suppressors. This merging reduces the number of separate components and cable runs needed, minimizing energy loss while maintaining reliability through centralized protection
2Adaptability or versatility
If hybrid cables with multiple DC circuits are used to feed several radios, then power distribution is achieved, but individual surge protectors for each DC circuit increase device complexity and space requirements
Solution Approach 1:
The hybrid cable assembly is designed as a universal distribution unit that can serve multiple radio units simultaneously through a single enclosure. The assembly provides multi-functionality by integrating data transmission, power distribution, and overvoltage protection in one standardized interface, reducing complexity compared to individual protectors for each circuit
3Ease of operation
If fiber optic breakout assemblies are installed in conventional cellular sites, then data connections are provided, but the space available is extremely limited and costly to rent
Solution Approach 1:
The patent merges fiber optic data connections and power distribution into a single hybrid cable assembly that terminates in one compact enclosure. This integration dramatically reduces the space footprint compared to conventional separate breakout assemblies, allowing installation in limited tower space without incurring high rental costs for additional equipment space
