Link failure diagnosis device of hand-hold passive optical network

Abstract

The invention relates to a failure diagnostic device for a passive optical network (PON) link, which comprises the following parts: an optical signal processing subsystem, a PON subsystem, a processor (CPU) subsystem, a user interface (I/O) subsystem, a business interface subsystem, a clock subsystem and a power subsystem. The primary function of the device comprises the physical layer testing, link layer testing, business layer testing of the PON interface and the display, record and preservation of the testing results. The device of the invention has distinct characteristics and advantages that: firstly, the device can make overall monitoring to the link situation of the PON system and all kinds of key parameters and can clearly position every failure of the PON system; secondly, the device is a handheld device with simple and flexible operation, which is suitable for the installation of the PON network equipments, project acceptance and maintenance applications; thirdly, a modularized structure can provide different testing functions by adding the VoIP business modules and IPTV business modules.

AI Technical Summary

Benefits of technology

This patented technology helps detect problems such as optical fibers being cut off due to environmental factors like temperature changes over time. It uses specialized components called support records for testing these conditions during normal use. These tests help identify any issues early on before they become critical because it provides valuable insights into how well your networks work properly.

Problems solved by technology

This patents describes how physical connections between different components like routers and servers may fail overtime due to factors like temperature changes and agitation caused by winds. To diagnose these issues, physicists often utilized special tools called Power Meters (PEM' s abbreviation from Electrical Meter Company Limited) to capture signals on their own wires. However, current methods require manual intervention during troubleshooting operations, making them difficult to implement continuously without interrupting normal communication sessions. Additionally, they lack flexibility when performing various analyzes needed.
