基于FPGA的计算机多媒体光纤传输设计与实现

Design and implementation of computer multimedia optical fiber transmission based on FPGA

为了满足计算机主机和外设在电磁屏蔽环境中电磁隔离的要求,提出了一种基于FPGA的光纤传输系统的设计方案。在ISE12.3开发环境下,采用Verilog语言,结合数字化技术与光纤传输技术,在四层PCB板上实现了计算机多媒体信号(VGA视频、音频等信号)在光纤中远距离低损耗的高速实时传输。

In order to meet the requirements of electromagnetic isolation between the host computer and peripherals in the environment of electromagnetic shielding,a design of optical transmission system based on FPGA was proposed.The distant fiber transmission of computer multimedia signals（VGA video,audio and other signals）,which was low-loss,high-speed and real-time,was achieved through the Verilog language and the combination of digital technology and fiber optic transmission technology by the four-layer PCB board in the development environment of ISE 13.2.
