ONT-to-Mobile Short-Range Link for Real-Time PON Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional PON troubleshooting requires extensive technician expertise and time to diagnose and repair network failures, often hindered by the need to transmit diagnostic information through optical fibers, which can fail during issues, and locating equipment within customer premises is challenging.
Innovation Solution
A client device directly connects to ONT or other PON components via short-range communication (Wi-Fi, Bluetooth, NFC) to receive real-time diagnostic information, providing step-by-step repair instructions through augmented reality overlays on a transparent display, and optionally ordering replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If diagnostic information is transmitted through optical fibers to a server for analysis, then centralized monitoring is achieved, but the process is slow and fails when optical fibers are damaged
Solution Approach 1:
The patent introduces a wireless communication intermediary (Wi-Fi, Bluetooth, or NFC) between the ONT and the client device, allowing diagnostic information to be transmitted without relying on the optical fiber infrastructure. This mediator enables alternative communication paths that remain functional even when optical fibers are damaged, resolving the contradiction between reliability and time loss.
Solution Approach 2:
The patent segments the diagnostic information transmission process into two independent channels: the optical fiber channel for data communication and the wireless communication channel for diagnostic purposes. This segmentation allows the diagnostic function to operate independently of the optical fiber status, improving reliability while reducing transmission time.
2Measurement precision
If technicians with years of experience are used for troubleshooting, then accurate diagnosis is achieved, but the cost and time for service increase
Solution Approach 1:
The patent implements a self-service diagnostic system where the ONT automatically collects and transmits diagnostic information to the client device, and the system provides guided troubleshooting instructions. This eliminates the need for technicians to physically locate and manually diagnose problems, allowing customers to resolve issues independently while maintaining high diagnostic accuracy through structured guidance.
Solution Approach 2:
The patent establishes a feedback loop where the ONT continuously monitors network parameters and transmits this information to the client device, which then provides real-time guidance to the user. This automated feedback system replaces the need for expert technicians by using algorithmic analysis of diagnostic data to guide troubleshooting steps.
3Ease of operation
If technicians physically locate equipment at customer premises, then direct access to hardware is achieved, but the process is time-consuming and complex
Solution Approach 1:
The patent replaces the mechanical process of physically locating and accessing equipment with a wireless communication system. The ONT transmits diagnostic information wirelessly to the client device, eliminating the need for technicians to physically travel to customer premises and locate equipment. This substitution of mechanical access with electronic communication dramatically reduces time while maintaining ease of operation.
4Measurement precision
If traditional troubleshooting procedures are followed, then comprehensive problem analysis is achieved, but the process requires extensive training and experience
Solution Approach 1:
The patent creates a universal troubleshooting system that can handle multiple types of network problems through a single integrated platform. The ONT collects various diagnostic parameters (signal strength, error rates, connection status) and the client device provides comprehensive analysis and guidance for different issue types, eliminating the need for specialized knowledge for each problem category while maintaining thorough analysis.

AI summary
Techniques for repairing a network failure in a Passive Optical Network (PON) include establishing a communication session with an optical network terminal (ONT) in a PON via a short-range communication link. In response to establishing the communication session, the techniques include receiving diagnostic information related to a network failure corresponding to the ONT, and presenting the diagnostic information to a user for the user to repair the ONT based on the received diagnostic information.
