摘要： 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.

The information transfer method includes: determining an indicator of a start bit in a protection time slot or a preamble time slot of a laser, and establishing a communication channel according to the indicator of the start bit; inserting Operation Administration and Maintenance (OAM) information of a Long Reach-Passive Optical Network (LR-PON) device into an upstream frame sent to an Optical Line Terminal (OLT) device by the LR-PON device at a position indicated by the indicator of the start bit, and transporting the upstream frame to the OLT device through the communication channel. Therefore, OAM functions of the LR-PON device are extended, so that the OAM information can be transported by the LR-PON device independently, and OAM characteristics of the LR-PON device are enhanced. For example, PON protection is better supported, and the speed and success ratio of protection switching of a PON system are increased.
