Abstract

The invention relates to a method and a device for upgrading firmware of an optical module and the optical module and relates to the technical field of optical communication. The method comprises the following steps: operating a firmware; receiving control information of the firmware; storing the control information of the firmware into a first region of a volatile storage region, wherein the first region is a region for storing the control information of the firmware in the volatile storage region; skipping firmware operation to operation and guidance for loading a Bootloader program; operating the Bootloader program to upgrade the firmware; storing caching information generated in a firmware upgrading process into a second region of the volatile storage region; and after upgrading the firmware, skipping to the operation of the upgraded firmware from the Bootloader program and obtaining control information of the firmware from the first region in a process of operating the upgraded firmware. According to the method and the device, provided by the embodiment of the invention, the possibility that a communication service is interrupted, caused by the fact that the optical module is upgraded, can be reduced.

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, used for photoelectric conversion. Such as 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 into an...
