PON ONT Direct Mobile Diagnostics for Fiber Network Failures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional PON network failures require extensive technical expertise and time for diagnosis and repair, as technicians often struggle to locate equipment within customer premises and interpret diagnostic information, especially when optical fibers are compromised.
Innovation Solution
A client device directly connects to an ONT in the PON via short-range communication (e.g., Wi-Fi, Bluetooth, NFC) to receive real-time diagnostic information, providing step-by-step repair instructions through augmented reality overlays on a transparent display, guiding users to locate and fix issues without needing extensive training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If technicians use conventional methods to diagnose PON network failures, then they can access diagnostic information through the optical network, but the process requires extensive technical expertise and time, and technicians struggle to locate equipment within customer premises
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the technician and the ONT. The mobile device establishes a direct short-range communication link with the ONT, serving as a mediator that can access diagnostic information without requiring the technician to have extensive expertise. The mobile device displays diagnostic information and repair instructions in an user-friendly format, making the diagnosis process easier while maintaining access to accurate technical data.
Solution Approach 2:
The system enables self-service by allowing the mobile device to automatically connect to the ONT and retrieve diagnostic information without requiring the technician to manually navigate complex network configurations. The ONT provides its own diagnostic data directly to the mobile device, and the system automatically interprets and presents the information, reducing the need for highly trained technicians.
2Reliability
If technicians manually locate and diagnose ONT equipment, then they can identify network failures, but the process is time-consuming and requires years of training and experience
Solution Approach 1:
The mobile device application prepares and displays diagnostic information and repair instructions in advance, before the technician needs to perform the actual repair. The system pre-fetches relevant data from the ONT and organizes it into step-by-step instructions, so when the technician arrives, the diagnostic work is already done or can be quickly completed, significantly reducing on-site time.
Solution Approach 2:
The system implements continuous feedback by having the mobile device communicate with the ONT to retrieve real-time diagnostic information. The ONT provides feedback about its operational status, and the mobile device processes this feedback to determine the nature of the failure and generate appropriate repair instructions, enabling quick and accurate diagnosis without extensive technician experience.
3Loss of information
If the ONT sends diagnostic information through the optical fiber network to the OLT and server, then centralized monitoring is achieved, but the information cannot be accessed when optical fibers are compromised or network failure occurs
Solution Approach 1:
The patent extracts the diagnostic information retrieval process from the conventional optical network pathway and implements it through a separate short-range communication channel. The mobile device directly connects to the ONT via Bluetooth, Wi-Fi, or NFC, bypassing the optical fiber network and OLT server infrastructure. This extraction ensures that diagnostic information remains accessible even when the optical network is compromised.
Solution Approach 2:
Instead of the traditional approach where the ONT sends information upstream to the OLT and server, the system inverts the communication direction by having the mobile device initiate and maintain a direct connection with the ONT. The mobile device pulls diagnostic information directly from the ONT rather than the ONT pushing information through the optical network, enabling access during network failures.
4Measurement precision
If technicians require extensive training and experience to interpret diagnostic information, then accurate problem identification is achieved, but the barrier to effective repair is high and repair efficiency is reduced
Solution Approach 1:
The system performs self-service by automatically interpreting diagnostic information and generating step-by-step repair instructions. The mobile device application processes the raw data from the ONT and presents it in an actionable format, eliminating the need for technicians to have extensive interpretive skills while maintaining accurate problem identification. The system does the cognitive work that previously required trained expertise.
Solution Approach 2:
The patent replaces the mechanical system of human expertise and experience with an automated information processing system. Instead of relying on technicians' brains and experience to interpret diagnostic data, the mobile device application automatically analyzes the information and generates repair instructions, substituting human cognitive processing with automated software logic.

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.
