Abstract

The invention discloses a firmware upgrade method and device for an optical module. The method includes: obtaining a firmware upgrade package, the firmware upgrade package includes a program header and a program body, the program header includes information identifying the type of firmware to be upgraded, and the program body includes update information for upgrading the firmware; according to the The program header of the firmware upgrade package determines the firmware type of the upgrade, and the firmware type at least includes a field programmable gate array FPGA or a micro control unit MCU; according to the firmware type, the program body is stored in the firmware with the determined upgrade In the storage medium corresponding to the type. It is realized that the program body of different firmware types is stored in the storage medium corresponding to the firmware type, so that multiple versions of the program body can be stored in the storage medium, so that the optical module can work normally, thereby improving the working efficiency of the optical module .

Description

technical field [0001] The invention relates to optical communication technology, in particular to a firmware upgrade method and device for an optical module. Background technique [0002] With the development of communication technology, optical modules are widely used in various aspects of communication technology. Among them, optical modules can realize photoelectric conversion, that is, the transmitting end of optical modules can convert electrical signals into optical signals, and the receiving end of optical modules can convert Optical signals are converted into electrical signals. [0003] While the rate of the optical module is increasing, that is, the rate of the optical module is increased from 10G, 40G to 100G, the Microcontroller Unit (MCU) in the optical module has been unable to meet the high-speed processing requirements of the optical module. In the prior art, a field-programmable gate array (Field-Programmable Gate Array, referred to as FPGA) is set in the ...
