光纤GbE+TDM融合通信技术的FPGA实现

FPGA implementation of optical GbE+TDM communication technology

为了解决新兴包交换网络与目前仍大量运行着的传统时分复用(TDM)电路交换网络的并存和融合问题,采用改进的8B/10B编解码方案,利用Verilog HDL语言在FPGA上实现GbE+TDM技术。经过PRBS信号测试可知,该TDM信号能与光纤GbE信号在原有的光纤线路上同时传输。

To solve the coexistence and integration problems between Emerging Packet-Switched network and traditional time division multiplexing（TDM） Circuit-Switched network,we adopted a modified 8B/10B encoding and decoding method to realize GbE＋TDM technology on FPGA with Verilog HDL language.After testing by PRBS,it is shown that the TDM signal together with optical GbE signal can be transmitted on original fiber channel.
