Solution Overview
Problem
Traditional radio head systems require multiple cables to be run up towers for signal transmission and power, leading to increased installation costs, space occupation, weight issues, and maintenance challenges due to the complexity of cable configurations.
Innovation Solution
A cable breakout assembly that uses a single power feeder cable to supply multiple amplifiers and enables data exchange, reducing the number of cables and connections by incorporating a compact, environmentally sealed design with crimped and sealed splice sections within a breakout enclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate cables are used for power and signal transmission to amplifiers at the top of the tower, then reliable power supply and signal transmission are achieved, but installation costs increase, space occupation increases, and maintenance complexity increases
Solution Approach 1:
The patent combines multiple separate cables (power cable and signal cables) into a single integrated hybrid cable assembly. The power conductor and optical fibers are bundled together within a common cable structure, eliminating the need for separate cable pulls and reducing installation complexity while maintaining reliable power supply and signal transmission to remote amplifiers.
Solution Approach 2:
The hybrid cable assembly serves multiple functions simultaneously: it provides electrical power transmission through the power conductor, optical signal transmission through the optical fibers, and mechanical support for mounting amplifiers. This multi-functional design reduces the overall system complexity and the number of components required.
2Adaptability or versatility
If multiple cables are run up the tower for power and signal, then all amplifiers can be powered and connected, but the number of cable pulls increases and tower space is occupied
Solution Approach 1:
The invention merges multiple cables into a single hybrid cable assembly that contains both power conductors and optical fibers. This single cable replacement reduces the quantity of cables from multiple separate cables to just one, while still providing connectivity to multiple amplifiers through the integrated components.
Solution Approach 2:
The hybrid cable is segmented into functional sections: a power cable portion with conductors for electrical power, and optical fiber portions for signal transmission. This segmentation allows each component to perform its specific function while being integrated in a single cable structure, reducing overall cable quantity.
3Productivity
If a single hybrid cable is used for both power and optical signals, then cable quantity is reduced and installation is simplified, but proper separation and protection of power and optical components is required
Solution Approach 1:
The hybrid cable assembly is divided into distinct sections: a power cable section containing electrical conductors and an optical cable section containing optical fibers. This segmentation allows for proper separation and protection of the two types of components while maintaining integration in a single cable structure, facilitating easier installation and maintenance.
Solution Approach 2:
The hybrid cable assembly acts as an intermediary structure that bridges the gap between separate power and optical cable systems. It provides a unified interface for connecting to amplifiers while internally maintaining the necessary separation between electrical and optical components, simplifying the connection process.
