Hybrid Power-Fiber Enclosure With Separate Trays for In-Line Tap-Offs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for providing power and data connectivity to remote network-connected devices, such as small cell base stations, are often expensive and time-consuming, especially in urban environments where installing composite power-data cables can be costly and labor-intensive.
Innovation Solution
The development of a power and fiber splice enclosure that allows for in-line distribution of both power cables and fiber optic data tubes, enabling tap-offs for power and fiber connections, and the creation of over-provisioned power and data connectivity micro grids that can be incrementally expanded, reducing the need for extensive cabling and third-party involvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If composite power-data cables are installed to provide power and data connectivity to remote devices, then power and data delivery capability is improved, but installation cost and time increase
Solution Approach 1:
The system segments power distribution into modular components: power distribution units (PDUs) with multiple outlets, separate power cables, and modular enclosures. This allows incremental deployment where power can be added in stages rather than requiring complete pre-installation of all cabling infrastructure.
Solution Approach 2:
The system enables preliminary power distribution infrastructure installation without requiring complete final configuration. Power cables and PDUs can be installed in advance, and remote devices can be connected as needed, reducing both initial installation time and complexity.
2Power
If composite power-data cables are installed to provide power and data connectivity, then power and data delivery capability is improved, but installation cost increases
Solution Approach 1:
The system divides the power distribution infrastructure into separate, standardized components: power cables, PDUs, enclosures, and mounting hardware. This modular approach allows each component to be optimized independently and assembled from readily available parts, reducing overall system cost compared to custom composite cables.
Solution Approach 2:
The system uses universal power cables and PDUs that can serve multiple functions and configurations. The same PDU can power different types of remote devices, and the modular design allows the infrastructure to be reused across multiple installations, reducing per-unit cost.
3Reliability
If extensive cabling infrastructure is installed to provide power and data connectivity, then connectivity reliability is improved, but device complexity and installation complexity increase
Solution Approach 1:
The system segments the power distribution into hierarchical levels: main power source, PDUs with multiple outlets, and individual device connections. This modular structure simplifies installation and troubleshooting compared to complex composite cable systems, while maintaining reliable power delivery through standardized interfaces.
Solution Approach 2:
The system enables self-contained power distribution units that can be independently installed and configured. Each PDU is a self-sufficient module with built-in circuitry and multiple outlets, reducing the need for complex external infrastructure and simplifying both installation and future expansions.
