20100135652 | FAULT DETECTING METHOD, SYSTEM, AND APPARATUS FOR PON SYSTEM - A fault detecting method, system, and apparatus for a PON system and an electrical relay apparatus are provided. The method includes the following steps. An electrical relay apparatus receives and detects a signal sent by a previous apparatus. If a defect is detected in the received signal, it is determined that a fault occurs to a transmission path between the previous apparatus and the electrical relay apparatus, and a signal with no defect is formed and sent to a next apparatus. If no defect is detected, the received signal is processed according to original processes and sent to the next apparatus. The next apparatus receives and detects the signal sent by the electrical relay apparatus. If a defect is detected in the signal sent by the electrical relay apparatus, it is determined that a fault occurs to a transmission path between the next apparatus and the electrical relay apparatus. | 06-03-2010 |
