FTTH As-Built Validation via Integrated Inventory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for validating the as-built of FTTH projects often result in inventory inconsistencies and failures to adhere to FTTH/GPON end-to-end rules, due to the lack of integration between ISP and OSP inventory systems.
Innovation Solution
A method that validates the as-built of FTTH projects by ensuring end-to-end inventory consistency and conformance to FTTH/GPON rules, specifically by verifying fibre connectivity, split ratios, and optical budgets across ODPs, using integrated ISP and OSP inventory databases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate inventory systems are used for ISP and OSP, then system complexity is reduced, but inventory consistency and end-to-end rule conformance deteriorate
Solution Approach 1:
The patent merges separate ISP and OSP inventory systems into a unified integrated inventory system. This integration enables end-to-end validation of FTTH projects by cross-checking connectivity, split ratios, and optical budgets across both domains, thereby ensuring inventory consistency and rule conformance without requiring separate validation processes
2Ease of manufacture
If separate validation processes are used for ISP and OSP, then process simplicity is maintained, but end-to-end rule conformance deteriorates
Solution Approach 1:
The validation process is segmented into distinct validation rules for connectivity, split ratios, and optical budgets, each handled by specialized validation modules within the integrated system. This segmentation allows complex end-to-end validation to be broken down into manageable checks while maintaining overall process precision and rule conformance
3Measurement precision
If complete project validation is required before service activation, then inventory accuracy is improved, but service activation time deteriorates
Solution Approach 1:
The system performs preliminary validation of critical connectivity and configuration parameters during the construction phase, allowing early detection and correction of issues. This enables partial validation and early service activation for approved segments while maintaining overall inventory accuracy through continuous validation updates

AI summary
The present invention provides new method to be used to validate the as-built of FTTH projects, based on the end-to-end inventory information and FTTH/GPON rules applied to ODP(s), to declare them “ready for service”. The method assures end-to-end (ISP and OSP) inventory consistency and FTTH/GPON rules conformance. Additionally, it allows the inventory of FTTH projects to be partially approved, the network operator may put on service parts of the project, as long as the network is being deployed and start selling FTTH services earlier. This method presents a new as-built validation paradigm, that verifies the readiness of service each ODP of an FTTH project, guaranteeing, the end-to-end fibre connectivity between the ODP and the OLT(s) located at the CO, the split ratio of each ODP access port follows the configured value (typically 1:64), and the estimated optical budget of each ODP access port is conformant to GPON attenuation standards.
