摘要：实现了面向未来无线通信的、基于可见光通信新兴技术的高速无线光互联系统，并且研制出出
光率高、带宽大的超薄LED 芯片，结合自主创新的高灵敏度接收模块、恒流恒压LED 驱动模块以及FPGA 高
速处理模块，从而设计实现了基于光互联的未来超高速无线网络系统。其作为新兴的网络节点互联方式，
完全可以替代目前的光缆，并且具备传统光缆所不具备的优势，如无需布线、体积轻便、组网方便等优
势。可见光通信作为未来高速无线通信的必经之路，无论是在速度、抗干扰能力、距离还是设备体积方
面，都具备传统通信互联手段不具备的优势。且对于目前病毒肆虐的现状，把有线变成无线，也可以在一
定程度上减少病毒的传播，方便人们的生活。

Abstract

A high-speed wireless optical interconnection system is realized based on the emerging visible
light communication technology for future wireless communication, and the ultra-thin LED chip with
high luminous rate and wide band width is devleoped. Combined with independent innovation of high-
sensitivity receiving module, constant current and constant voltage LED driver module and FPGA
high-speed processing module, the future ultra-high-speed wireless network system is designed and
implemented based on the optical interconnection. As a new way for the network node interconnection,
it can completely replace the current optical cable, and has the advantages that traditional optical
cable does not have, such as no wiring, light volume, convenient networking and so on. A visible light
communication as the only way for the high-speed wireless communication in the future, whether in terms
of speed, anti-interference ability, distance or equipment volume, has the advantages that traditional
communication interconnection means do not havee And for the current situation of virus rampant,
transforming the wired optical interconnection system into the wireless network optical interconnection
system,the scheme can reduce the spread of the virus to a certain extent, thus it is convenient for
people’s lives.
