基于FPGA的万兆以太网传输设备设计

Design of 10G ethernet transmission equipment based on FPGA

为了延伸IP交换机的以太网用户线和以太网中继线,提出了基于光纤通信的传输距离可达20千米以上的万兆以太网传输方案。该方案由4个10M/100 M/1000Mbps自适应以太网接口和1个10Gbps光接口组成。利用Altera公司Arria V GT系列FPGA芯片实现了4个以太网接口和1个光接口之间的数据转换功能。

In order to extend the subscriber line and trunk line of IP switches, a 10G ethemet transmission solution is proposed based on optical fiber communication, the transmission distance is up to 20kin above. The program consists of four 10/100/1000Mbps adaptive ethemet interfaces and a 10Gbps optical interface. Using Altera＇s Arfia V GT FPGA realized the data conversion function between four Ethemet interfaces and an optical interface.
