Embodiment Construction

[0022] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0023] like figure 2 As shown, in the optical network system, the host computer 20 is a device for controlling and monitoring the operation of the optical module 10 . The host computer 20 can control and monitor the work of multiple optical modules 10 through an I2C (Inter-Integrated Circuit) bus. The optical module 10 is an integrated optical transceiver module for photoelectric conversion. ...

Abstract

The invention relates to a method, a device and an optical module for upgrading the firmware of an optical module, and relates to the technical field of optical communication. The method includes: running firmware; receiving control information of the firmware; storing the control information of the firmware in a first area of ​​the volatile storage area; the first area is an area used to store the control information of the firmware in the volatile storage area; Jumping from running the firmware to running the bootloader program, by running the Bootloader program, the firmware is upgraded, and the cache information generated in the firmware upgrade process is stored in the second area of ​​the volatile storage area; the firmware After the upgrade is completed, jump from running the Bootloader program to running the upgraded firmware, and obtain the control information of the firmware from the first area during the running of the upgraded firmware. The embodiments of the present invention can reduce the possibility of interruption of communication services caused by optical module upgrades.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a method and device for upgrading firmware of an optical module and an optical module. Background technique [0002] An optical transceiver integrated module, referred to as an optical module, is a standard module in equipment in the field of optical communication, which is used for photoelectric conversion. like figure 1 As shown, the optical module 10 is composed of an optical transmitter 101, an optical receiver 102, a microprocessor 103 and the like. Wherein, the microcontroller 103 of the optical module 10 and the microprocessor 103 control the optical transmitter 101 to convert the electrical signal into an optical signal, and the optical transmitter 101 transmits the optical signal to the optical fiber. The optical receiver 102 of the optical module 10 can receive the optical signal transmitted by the optical fiber, and convert the received optical signal i...
