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.

Embodiment Construction

[0047] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0048] Aiming at the problem that there is no portable PON link fault diagnosis device at present, the present invention provides a hand-held device for PON network link state monitoring and fault diagnosis.

[0049] Fig. 1 introduces the PON network topology related to the device of the present invention. It can be seen from the figure that an OLTPON port can be connected to multiple ONUs through an optical splitter. The downlink data transmission method from the OLT to the ONU is a time-division multiplexed physical layer broadcast method, that is, each downlink frame will be sent to the PON ports of all ONUs. The uplink data transmission mode from ONU to OLT is TDMA (for EPON and GPON), that is, each ONU sends uplink data in the uplink time slot allocated by OLT for its own use.

[0050] Fig. 2 has introduced the typical appl...
