SFP (Small Form-Factor Pluggable) optical module upgrading method based on Bootloader

Abstract

The invention discloses an SFP (Small Form-Factor Pluggable) optical module upgrading method based on a Bootloader. The SFP optical module upgrading method comprises the following steps: opening up a Bootloader storage area in a FLASH area of a microcontroller of an SFP optical module, wherein a Bootloader startup program is stored in the storage area; selecting to start the Bootloader and upgrading data in a program code area in the FLASH area. The SFP optical module upgrading method has the benefits that a Bootloader technology is applied to the field of optical modules, so that a user or a manufacturer can remotely upgrade a microcontroller program of the optical module through a network without returning a factory to use a programmer writing program; through a remote upgrading technology, an optical module internal program can be upgraded according to different target switches and routers so as to achieve the purpose of compatibility; meanwhile, effective data or debugging and test parameters cannot be lost.

Description

technical field [0001] The invention relates to the field of optical modules, in particular to a bootloader-based SFP optical module upgrading method. Background technique [0002] An optical module is an integrated communication accessory that provides photoelectric-to-electrical-optical conversion capabilities. Its internal structure is shown in figure 1 shown. Among them, the main function of the microcontroller is to provide a communication bus hardware interface with the host computer and a warning and alarm hardware interface. At present, mainstream optical modules on the market contain programmable microcontrollers. SFP is the most common optical module on the market, generally used for Gigabit Ethernet. [0003] As an important component of switches and routers, optical modules are widely used in network communication hardware. There are a large number of manufacturers of switches and routers, well-known manufacturers include: Cisco, Huawei, ZTE, Alcatel, HP, TP-...

AI Technical Summary

Problems solved by technology

Due to the disassembly of the shell, the performance parameters of the product may change, so it is necessary to test the performance of the optical module again

This will introduce a huge workload, and due to the disassembly of the shell parts, a certain percentage of material damage will be caused, and the cost of program upgrades will also be greatly increased.

[0013] Some optical module manufacturers, through the design of the circuit board, avoid the disassembly of the optical module shell and the connection of the programming cable, but they must match their special program to upgrade the circuit board, which also prevents customers from doing it themselves or with remote assistance. Complete the program upgrade

At the same time, the design of this type of circuit will increase the cost and reduce the reliability of the optical module
