SFP+双MCU光收发模块升级的设计与实现

Research of Upgrade Scheme Based on Two MCUs SFP + Optical Transceiver

随着光模块通讯速率的不断提高和功能的不断增加,很多时候由于PCBA(Printed Circuit Board+Assembly)本身面积的局限性等原因只能使用多块MCU来代替一块多PIN脚的MCU。于是,在一个模块中出现了多MCU并存的情况。针对该情况,提出了一种在双MCU光模块中迅速、快捷更新驱动程序的方法,并以SFP+波长可调谐光模块系统更新为例,给出了该方法的详细设计流程和实验结果。该方法被证实可行有效。

With the constant improvement of the optical module communication rate, in practical applications because of the area limitation and other reasons, it has to use more than one MCU instead of a PIN foot MCU. So that more than one MCU will be coexist. For this kind of situation, a fast in double MCU module light, quick update driver method is proposed in this paper. Taking the SFP ＋ wavelength tunable optical module system update as an example, it gives the detailed design process and the experimental results of this method. The method is proved feasible and effective.
