Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current undersea optical communication systems face challenges in efficiently managing and optimizing separate communication and detection networks over long distances, where the existing systems often require complex and costly infrastructure to maintain separate power and signal pathways for high-bit-rate communication and low-bit-rate detection signals.
Innovation Solution
The system employs a single optical fiber cable with separate fibers for communication and detection networks, powered by a common power feed equipment, allowing for separate optimization and minimization of costs and complexity by maintaining entirely separate transmission paths with optional coupling of signals between components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate power and signal pathways are maintained for communication and detection networks, then reliability and independence of each network is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent combines communication and detection networks into a single optical fiber cable infrastructure, where both networks share the same cable, power conductors, and housing. This merging reduces device complexity and installation cost while maintaining separate signal pathways for reliability. The shared infrastructure includes common power feed equipment and repeaters that serve both networks.
Solution Approach 2:
The optical fiber cable and its associated elements are designed to serve multiple functions simultaneously - carrying both communication signals and detection signals through separate fibers, providing power to both networks through shared power conductors, and housing both networks within a common protective structure. This multi-functionality reduces overall system complexity while maintaining network independence.
2Reliability
If separate optimization of communication and detection networks is implemented, then performance of each network is improved, but installation and maintenance complexity increases
Solution Approach 1:
The patent segments the optical fiber cable into distinct functional sections - communication network elements (repeaters, transceivers) and detection network elements (sensors, detectors) - allowing each to be independently optimized for its specific performance requirements. Each network can be configured with appropriate components and parameters without compromising the other network's performance.
Solution Approach 2:
The patent introduces intermediary elements such as optical couplers, multiplexers, and shared repeaters that enable independent optimization of both networks while simplifying installation and maintenance. These intermediaries allow separate signal pathways to coexist within a unified infrastructure, enabling independent configuration and optimization without requiring completely separate physical installations.
3Device complexity
If common power feed equipment is used for both networks, then cost and complexity are reduced, but power management complexity increases
Solution Approach 1:
The power feed equipment is designed to universally serve both communication and detection networks through shared power conductors in the optical cable. The same power amplifiers, power distribution units, and power management circuits provide power to both networks, reducing infrastructure complexity and cost while enabling centralized power management that simplifies operation rather than complicating it.
4Reliability
If entirely separate transmission paths are maintained, then network independence and reliability are improved, but cost and complexity increase
Solution Approach 1:
The patent merges the physical infrastructure for both networks into a single optical fiber cable, where separate transmission paths for communication and detection signals are achieved through separate optical fibers or wavelength channels within the same cable. This approach maintains network independence and reliability through separate signal pathways while reducing the total quantity of infrastructure materials needed compared to completely separate cables and installations.

AI summary
An optical communication system supporting detection and communication networks. A communication network transmission path and the detection network transmission path are provided as separate paths established by separate fibers or fiber pairs of the same optical fiber cable. All of the elements coupled to the communication network transmission path and the detection network transmission path may be powered by the same power feed equipment through the same optical fiber cable power conductor.
