Embodiment 1
[0052] Please refer to image 3 Figure 4 and Figure 5 , Embodiment 1 of the present invention is: a method for reporting a failure of an optical fiber communication link, wherein a microprocessing unit (MCU) is arranged in the optical fiber transceiver, and the MCU is connected to the optical transmission control port and the SMI interface of the optical fiber transceiver;
[0053] During the power-on process of the system, the micro-processing unit checks the connection status of the optical fiber port and the twisted-pair port by means of connectivity detection (for example: by means of SMI (Serial Management Interface, interface or port connection indicator light, etc.);
[0054] When the optical fiber port and the twisted pair port are connected normally or not connected, the micro-processing unit is in a circular query state;
[0055] When a connection fault occurs at the optical fiber port, the micro-processing unit detects the fault and forcibly closes the twisted p...

The invention discloses a method for reporting faults of optical fiber communication links. The method includes: detecting that whether the optical fiber port and the twisted-pair port of an optical fiber transceiver are simultaneously positioned in a connected state or a disconnected state, if yes, circularly detecting the optical fiber port and the twisted-pair port, and if no, detecting that whether the optical fiber port or the twisted-pair port has a connection fault; when detecting that the optical fiber port has the connection fault, setting a register corresponding to the twisted-pair port by an SMI (Serial Management Interface) to close the twisted-pair port forcibly; when detecting that the twisted-pair port has the connection fault, setting a register corresponding to the optical fiber port by an SMI, or forcibly disconnecting the power supply circuit of the optical transmitting circuit of the optical fiber port; marking the optical fiber transceiver, which has been firstly subjected to connection fault detection, in the optical fiber communication link by an LED lamp. According to the method, link faults of devices of the plurality of points in the optical fiber communication link can be accurately detected and positioned. The invention also discloses a device for reporting the faults of the optical fiber communication links.
Description
technical field [0001] The invention relates to the field of optical fiber communication, in particular to a method and device for reporting a failure of an optical fiber communication link. Background technique [0002] At present, in the optical fiber communication system, optical fiber transmission equipment mostly adopts optical fiber transceiver (MC, Media converter). The optical fiber transceiver includes an optical fiber port and a twisted pair port. , the connection between the two points follows the IEEE802.3 standard (100Base-FX or 1000Base-X). Each optical fiber port in the optical fiber transceiver includes a receiving end (RX) and a transmitting end (TX). The main control chip of the optical fiber transceiver adopts the method of pure hardware implementation. The main control chip judges whether the optical fiber port receives the optical signal or the electrical signal of the twisted pair port. When any signal is not received, the main control chip is forcibly...
