Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual upgrades of Passive Optical Network (PON) network terminals disrupt user life and increase maintenance costs, as they require physical intervention and can't automatically adapt to changing bandwidth demands, leading to inefficient resource utilization.
Innovation Solution
The method involves automatically upgrading the optical fiber line rate of the central office device and synchronizing the network terminal device's line rates with the central office device's clock and configuration information, allowing for automatic adaptation of upstream and downstream line rates without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If manual upgrading or replacing of network terminals is performed, then the network rate can be upgraded, but user life is disrupted and communication is interrupted
Solution Approach 1:
The network terminal device automatically extracts clock information from downstream data flows and adjusts its own working rates without manual intervention. The system performs self-upgrading by extracting timing information from received optical signals and automatically configuring upstream and downstream line rates, eliminating the need for manual terminal replacement while maintaining user convenience
Solution Approach 2:
The invention changes the working rate parameters of the network terminal device dynamically. By extracting clock information from downstream data flows, the terminal automatically adjusts its upstream and downstream line rates to match the upgraded optical fiber line rate, enabling rate upgrading through parameter modification rather than hardware replacement
2Speed
If manual upgrading or replacing of network terminals is performed, then the network rate can be upgraded, but network maintenance cost increases
Solution Approach 1:
The network terminal device performs automatic rate adaptation by extracting clock information from downstream data flows and self-configuring its working rates. This self-service mechanism eliminates the need for manual intervention in rate upgrading, reducing maintenance complexity and costs while enabling network rate upgrades
Solution Approach 2:
The system uses feedback from downstream data flows to automatically adjust terminal working rates. The terminal extracts clock information from received optical signals and uses this feedback to synchronize and configure its upstream and downstream line rates, creating a closed-loop automatic rate adaptation mechanism that simplifies maintenance
3Speed
If manual upgrading or replacing of network terminals is performed, then the network rate can be upgraded, but original network resources are wasted
Solution Approach 1:
The invention enables rate upgrading by changing the working rate parameters of existing network terminal devices through automatic clock extraction and synchronization. This allows the original terminal hardware to be reused at higher rates by modifying its operational parameters, preventing waste of existing network resources while achieving rate upgrade goals
