Submarine Cable Branching Layout for Reconfigurable Network Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing submarine cable systems lack adaptability in responding to changes in communication demand, as the connection between submarine cables cannot be altered after initial laying, limiting flexibility in network configuration.
Innovation Solution
A method involving the laying of trunk submarine cables with branching apparatuses and connecting a branch submarine cable between them, allowing for dynamic reconfiguration of connections in response to changing communication needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed connection structure is used for submarine cables, then the initial network configuration is achieved, but the system cannot adapt to changes in communication demand
Solution Approach 1:
The submarine cable system is segmented into separate trunk cables and branch cables that can be independently laid and connected. The branching apparatus provides multiple connection points, allowing the system to be divided into modular units that can be configured flexibly based on communication demands without requiring complete system redesign.
Solution Approach 2:
The cable connection structure transitions from a static, fixed configuration to a dynamic system where branch cables can be connected or disconnected from trunk cables at branching apparatus. This dynamic capability allows the system to adapt to changing communication demands by reconfiguring connections between land stations and cable systems.
2Adaptability or versatility
If trunk submarine cables are laid without branching apparatus, then the cable structure is simple, but connection flexibility and adaptability are lost
Solution Approach 1:
The branching apparatus serves multiple functions: it provides connection points for multiple branch cables, maintains signal transmission between trunk cables, and enables flexible reconfiguration of network topology. This multi-functional device allows a single component to address various connection scenarios without requiring separate specialized equipment for each function.
Solution Approach 2:
The branching apparatus acts as an intermediary component between trunk submarine cables and branch cables. It mediates the connection between these cable types, providing a standardized interface that simplifies the overall system architecture while enabling flexible connections without requiring direct complex interconnections between all cable endpoints.
3Productivity
If submarine cables are laid with predetermined connections, then the laying process is straightforward, but post-laying adaptability is eliminated
Solution Approach 1:
The trunk submarine cables are laid in advance with branching apparatus installed at predetermined locations, but the actual connections to branch cables are deferred until needed. This preliminary action allows the infrastructure to be prepared and positioned efficiently, while the connection configuration can be optimized later based on actual communication demands without requiring changes to the laying process itself.
