Engineering Contradiction Analysis
1Adaptability or versatility
If EPON protocol is used for optical fiber connectivity, then Ethernet-based IP equipment connectivity is achieved, but integration with coaxial networks is difficult
Solution Approach 1:
The patent introduces a coaxial media converter (CMC) as an intermediary device that bridges the EPON optical network and the coaxial network. The CMC performs protocol conversion and signal transformation, enabling seamless integration between the two different network types without requiring complex reconfiguration of existing infrastructure.
Solution Approach 2:
The hybrid EPON-EPoC network architecture is designed to support multiple protocols and transmission media simultaneously. The system can handle both optical fiber transmissions (EPON) and coaxial cable transmissions (EPoC) through a unified network structure, providing multi-functionality and adaptability across different network segments.
2Reliability
If auto-negotiation is implemented over coaxial links, then reliable data transmission is achieved, but the negotiation process complexity increases
Solution Approach 1:
The auto-negotiation procedure is initiated during the link establishment phase before actual data transmission begins. The CMC and CNU perform spectral analysis, bandwidth determination, and power level negotiations in advance, ensuring that all transmission parameters are optimized and agreed upon before live traffic flows, thereby ensuring reliability without adding ongoing complexity.
Solution Approach 2:
The auto-negotiation process incorporates feedback mechanisms where the CMC and CNU exchange information about available bandwidth, power levels, and spectral characteristics. This bidirectional communication allows both devices to adjust their transmission parameters based on real-time channel conditions, ensuring reliable link establishment through adaptive optimization.
3Productivity
If bandwidth and power optimization is performed, then data transmission efficiency is improved, but control and management complexity increases
Solution Approach 1:
The system implements dynamic bandwidth and power allocation that adapts to changing network conditions and service requirements. The CMC can allocate different bandwidth portions and power levels to various services (voice, data, video) based on real-time demands, optimizing transmission efficiency while using automated control algorithms to manage the complexity of resource allocation.
