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 (SerialManagement 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 pa...

Abstract

The invention discloses a method for reporting a failure of an optical fiber communication link. line port, if not, detect whether it is a fiber port connection failure or a twisted pair port connection failure; when the fiber port connection failure is detected, set the register corresponding to the twisted pair port through the SMI interface, and forcibly close the twisted pair port ;When the twisted pair port connection failure is detected, set the register corresponding to the fiber port through the SMI interface, or forcibly disconnect the power supply circuit of the optical transmission circuit of the fiber port; use the LED light to identify the connection failure first in the fiber communication link Fiber Transceiver. The method can accurately detect and locate link faults of devices with multiple ports in the optical fiber communication link. The invention also discloses a device for reporting the failure of the optical fiber communication link.

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...
