Method for quickly downloading optical module firmware

Abstract

The invention discloses a method for quickly downloading optical module firmware, and relates to the technical field of optical communication networks, and the optical module firmware downloading board comprises an optical module which is used for downloading optical module firmware; The analog switch is used for being communicated with an appointed optical module downloading bus; The first microprocessor is responsible for firmware downloading of all the optical modules; The second microprocessor is responsible for in-place signal detection of all the optical modules and module firmware downloading state display; The optical module firmware downloading state display circuit is used for displaying the optical module firmware downloading state; The interface circuit is used for connecting the optical module firmware downloading board and the upper computer; And the power supply circuit is used for providing a working power supply for all parts of the optical module firmware downloadingboard. According to the method for quickly downloading the optical module firmware, the optical module firmware downloading efficiency can be greatly improved, the production line capacity can be improved, the production efficiency can be improved, the labor cost can be reduced, and firmware downloading of a plurality of optical modules can be realized by using the testing device of the optical module firmware downloading plate.

Description

technical field [0001] The invention relates to the technical field of optical communication networks, in particular to a method for quickly downloading firmware of an optical module. Background technique [0002] As the core device of the optical fiber access network, the optical transceiver module promotes the development of the trunk optical transmission system in the direction of low cost. The optical module is a photoelectric conversion module composed of optoelectronic devices, functional circuits and optical interfaces. The optical module is mainly used for The optical signal is sent and received. The optical signal is connected to the optical module through the optical fiber, which can convert the optical signal into an electrical signal. At the same time, the information of the electrical signal can be converted into an optical signal through the optical module, and then sent out through the optical fiber. The optical module is also called optical fiber. module. ...

AI Technical Summary

Problems solved by technology

[0004] In the production of large-scale optical modules, the speed of firmware download is very important. If the firmware download of each module can be improved a little bit, it will be very important for large-scale production, which will greatly increase production capacity and improve Production efficiency can save human resources and reduce labor costs at the same time. Therefore, it is very important to increase the speed of downloading the firmware of the optical module. However, the existing technology is only to download the firmware of a single optical module. After the download is complete, remove the module, and then Plug in another module to download the firmware, which will make the operator frequently plug and unplug the optical module, resulting in too much time being wasted. In this invention, a method for quickly downloading the firmware of the optical module is introduced to improve Speed ​​of downloading optical module firmware
