Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current connection interface assemblies for managing cables on antenna towers in Fiber to the Antenna (FTTA) networks lack effective protection against harsh environmental conditions and efficient cable management solutions, particularly for optical cables using CWDM or DWDM modules.
Innovation Solution
A connection interface assembly comprising a base module, a cable connection module with integrated CWDM or DWDM modules, and an enclosure that provides a watertight seal and cable organization features, including a fiber tray and cover, to protect fiber optic cables from environmental conditions and facilitate efficient cable routing and splitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable connection modules are mounted on antenna towers in FTTA networks, then cable management and signal transmission are enabled, but the assembly lacks effective protection against harsh environmental conditions
Solution Approach 1:
The patent combines multiple protective functions into a single integrated enclosure structure. The enclosure merges weather sealing, cable management, and module mounting functions into one unified component that protects the cable connection module while organizing fibers and managing cables simultaneously.
Solution Approach 2:
The enclosure employs a watertight seal design with gaskets or sealing membranes that flexibly adapt to the cable connection module while providing environmental protection. This flexible sealing approach ensures reliability against harsh conditions without adding rigid structural complexity.
2Ease of operation
If traditional cable management solutions are used, then basic cable routing is achieved, but cable routing complexity increases and installation becomes less efficient
Solution Approach 1:
The enclosure divides cable management into segmented sections with dedicated pathways for different cable types and fiber routing zones. This segmentation organizes the complex cable management task into manageable sections, reducing routing complexity and improving installation efficiency.
Solution Approach 2:
The enclosure acts as an intermediary structure between the external cable environment and the internal cable connection module. It provides a controlled transition zone with integrated cable access points and fiber routing channels that simplify the connection process.
3Adaptability or versatility
If additional cables are installed after initial feeder cable installation, then network flexibility is improved, but routing complexity and installation difficulty increase
Solution Approach 1:
The enclosure is pre-configured with multiple cable access points, routing channels, and expansion spaces during initial installation. This preliminary preparation allows additional cables to be installed later without requiring complex retrofits or difficult routing through already-installed structures.
Solution Approach 2:
The enclosure design incorporates universal cable access and routing capabilities that accommodate both initial feeder cable installation and subsequent additional cable installations. The same structure serves multiple functions: initial cable protection, ongoing cable management, and future expansion support.
