摘要
光纤到户以巨大宽带支持未来所有业务,赢得接入宽带网的最终解决方案.光纤到户远端设备必须解决数据业务、时分复用业务和有线电视业务的高速传输问题.首先提出基于以太网的无源光网络实现方案,采用基于VxWorks的处理器850插板的控制核心、5个功能模块化(底层驱动模块、系统管理模块、主从通信模块、主备倒换模块、命令行处理模块)的设计方法.通过采用broadcom5380、zarlink50114交换芯片和teko3701芯片,光纤到户远端设备不仅实现承载高速的数据业务和2.048Mb/s专线业务,而且可以动态地调整逻辑链路的带宽.吞吐量、时延、丢包率等性能测试结果表明,远端设备具有良好的扩展性、灵活性、移植性,能快速响应用户的各种需求,全面提高用户的服务质量.
Fiber to the home(FTTH)with huge broadband supports all future business,and wins the final solution of broadband network.FTTH far-end equipment must solve high speed transmission of data service,time division multiplexing service and cable television service.The realization scheme of ethernet passive optical network was put forward,which was based on the core of VxWorks MPC850 control board,designed with five function modules(driver module,system management module,communication module,main/standby switch module,command line processing module).By broadcom5380,zarlink50114 switching chip and teko3701 chip,FTTH far-end equipment realized bearing high-speed data service and 2.048Mb/s line service,and could dynamically adjust the logical link bandwidth.Based on the throughput,delay,packet loss rate and other performance test,the result shows that far-end equipment has good scalability,flexibility,portability,quickly responses to the various needs of users,and comprehensively improves the quality of user service.
