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... 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。 展开更多

Compact, hot-pluggable, and data-agnostic, SFP modules bring up to 4.25 Gbps to a flexible new form factor. The SFP transceiver which is the core device of optical communication is always the research focus in the field of optical communication for both telecommunication and data communication applications. The working principles of SFP including the transmitter components, the receiver components and the microcontroller are discussed in detail. The basic theory of high-speed signal and the concept of high - speed circuit, high-speed board design techniques are presented. A new design of high performance, cost effective SFP transceiver and PCB layout are also presented. The performance of the transceiver is analyzed and the characteristics of the sample are coincident with the expected ones. The status of the transceiver can be monitored and controlled by F C bus through the interface in real time. This transceiver can meet the requirement of SFF-8472. 展开更多
