Optical Module Status Identification via Sub-Period Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for identifying the state of optical modules in Optical Network Units (ONUs) lack accuracy, leading to potential misconfiguration and inefficiencies in service delivery within Passive Optical Networks (PONs).
Innovation Solution
A method that divides the identification period into sub-periods, where a Central Processing Unit (CPU) requests parameters from the optical module and tracks successful acquisitions, determining the module's state based on the number of successful sub-periods and previous identification states, allowing for automatic configuration of the PON MAC chip.

Engineering Contradiction Analysis
1Measurement precision
If the optical module state identification uses a simple single-period method, then the identification process is fast and simple, but the identification accuracy is low leading to potential misconfiguration
Solution Approach 1:
The identification period is divided into multiple sub-periods (first sub-period, second sub-period, etc.), allowing the system to perform multiple detection attempts within a complete identification cycle. This segmentation enables more comprehensive state verification while maintaining a structured and manageable identification process.
Solution Approach 2:
The system performs periodic identification by dividing the identification period into repeating sub-periods, where parameter acquisition attempts are made at regular intervals. This periodic approach allows the system to gather multiple samples of optical module state information, improving reliability through repeated measurements while maintaining a predictable identification rhythm.
2Extent of automation
If manual configuration is used for optical module state, then configuration accuracy can be verified, but manpower and time requirements increase
Solution Approach 1:
The PON MAC chip performs automatic self-configuration based on the identified optical module state. The system autonomously determines whether to operate in 1G or 10G mode without requiring manual intervention, thereby improving automation extent while maintaining reliability through the robust multi-sub-period identification mechanism that ensures accurate state detection before configuration.
3Adaptability or versatility
If optical modules are frequently inserted and removed, then system flexibility and adaptability improve, but identification reliability may deteriorate due to transient states
Solution Approach 1:
The system performs preliminary detection in the first sub-period before making final state determination. This preliminary action allows the system to detect transient states (such as modules being inserted or removed during operation) and distinguish them from stable states, thereby maintaining identification reliability even when modules are frequently changed.
Solution Approach 2:
The multi-sub-period identification structure provides a buffer against transient errors. By requiring consistent detection across multiple sub-periods, the system cushions against misidentification caused by temporary states during module insertion or removal, ensuring that only stable, genuine states trigger configuration changes.
