RF Chassis With Integrated Power Bus For Mixed Active Passive Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RF management systems in the telecommunications industry lack flexibility and versatility, as they often cannot accommodate both active and passive RF modules with different cable connectors and management solutions, limiting their configuration and reconfiguration capabilities in CATV head end environments.
Innovation Solution
A modular RF management system featuring a rack-mountable chassis with an integrated power bus, capable of hosting both active and passive RF modules, along with 'hot-swappable' power supply modules and various cable management structures, allowing for flexible configuration and reconfiguration to suit different requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior art chassis components are designed for specific module types, then module compatibility is improved, but system versatility deteriorates
Solution Approach 1:
The chassis component is designed with universal mounting structures that can accommodate both active RF modules (with power requirements) and passive RF modules (without power requirements). The power bus system provides power distribution capabilities that can be selectively engaged, allowing the same chassis to support different module types interchangeably, thereby achieving multi-functionality and resolving the contradiction between compatibility and versatility.
2Stability of the object's composition
If RF modules are provided with fixed cable connectors, then connection stability is improved, but configuration flexibility deteriorates
Solution Approach 1:
The cable management system incorporates dynamic elements such as movable cable guides, adjustable clamps, and flexible routing channels that can be repositioned to accommodate different cable connector types and configurations. This dynamic adaptability allows the system to maintain stable connections for installed modules while enabling flexible reconfiguration when module types or cable arrangements change, resolving the contradiction between connection stability and configuration flexibility.
3Quantity of substance
If chassis components are designed for high-density module mounting, then space utilization is improved, but module accessibility deteriorates
Solution Approach 1:
The chassis is segmented into modular sections with standardized mounting positions, allowing modules to be densely packed while maintaining uniform access points at the front panel. The power bus and cable management systems are also segmented into modular components that can be independently accessed and serviced, enabling high-density mounting without compromising the ease of installation, maintenance, and reconfiguration of individual modules.

AI summary
An RF management system especially suitable for use in CATV head end environments is disclosed. The system is characterized by a basic rack-mountable chassis component that can be configured for both front and rear mount applications, for different cable management solutions and for accepting eighteen passive RF modules or nine active RF modules or a combination of passive and active RF circuit modules. The active configuration of the chassis has an integrated power bus with at least nine connectors for receiving up to nine active RF circuit modules. The active RF circuit modules, such as power supplies and amplifiers are each provided with a “floating” connector for ease in connecting the power supply module or amplifier module to the power bus. The RF power supply module is capable of supplying power to all the active RF modules in the chassis as well as to active RF modules mounted in one or more other chassis in the rack.
