Optical-Fibre Coupling Protocol Switching for Hybrid PON Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical-fibre coupling devices are often preconfigured with a single protocol (XG-PON or XGS-PON) and may incorrectly integrate networks using the less efficient protocol, failing to adapt to hybrid networks requiring compatibility with both.
Innovation Solution
An optical-fibre coupling device that can detect reference information fields (Alloc-Id) to identify the protocol used by the network termination equipment and reconfigure itself to operate with the most efficient protocol (XGS-PON) using predefined identifiers (1022 and 1023) after physical synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the optical-fibre coupling device is preconfigured with a single protocol (XG-PON or XGS-PON) in the factory, then the device complexity is reduced and manufacturing is simplified, but the device cannot adapt to hybrid networks and may incorrectly integrate networks using the less efficient protocol
Solution Approach 1:
The patent implements dynamic protocol configuration by allowing the coupling device to change its operating protocol after deployment. The device detects the network protocol through reference information fields and reconfigures itself accordingly, transitioning from a static preconfigured state to a dynamic adaptive state. This resolves the contradiction by maintaining manufacturing simplicity while enabling post-deployment adaptability.
Solution Approach 2:
The patent changes the operational parameters of the coupling device based on detected network conditions. By monitoring reference information fields containing protocol identifiers and adjusting configuration parameters accordingly, the device can switch between XG-PON and XGS-PON protocols. This parameter-based adaptation resolves the contradiction between fixed manufacturing configuration and flexible network adaptability.
2Productivity
If the coupling device automatically integrates the network using the first detected protocol, then the integration speed is improved, but the transmission speed may be suboptimal if a more efficient protocol is available
Solution Approach 1:
The patent performs preliminary detection of protocol identifiers through reference information fields before finalizing the integration configuration. This preliminary action allows the device to identify the optimal protocol (XGS-PON for 10 Gbps uplink) before committing to integration, preventing suboptimal protocol selection while maintaining efficient integration throughput.
Solution Approach 2:
The patent implements a feedback mechanism where the coupling device continuously monitors reference information fields for protocol identifiers and adjusts its configuration based on this feedback. This feedback loop ensures that the device selects the most efficient protocol (XGS-PON when available) rather than merely accepting the first detected protocol, thereby optimizing transmission speed while maintaining integration efficiency.
3Adaptability or versatility
If the coupling device is configured to support both XG-PON and XGS-PON protocols, then the adaptability to hybrid networks is improved, but the device complexity increases
Solution Approach 1:
The patent implements multi-functionality by designing the coupling device to support both XG-PON and XGS-PON protocols within a single device architecture. The device contains configuration capabilities for multiple protocols but uses detection mechanisms to activate only the appropriate one, achieving universality without requiring separate dedicated devices for each protocol type.
Solution Approach 2:
The patent extracts the protocol identification function by specifically monitoring reference information fields for protocol identifiers. This extraction approach allows the device to selectively activate only the necessary protocol configuration (XG-PON or XGS-PON) based on detected network conditions, reducing the effective complexity by not simultaneously maintaining both protocol stacks active, while still preserving adaptability to hybrid networks.
