光纤到户远端设备的设计与测试
Design and test of fiber to the home far-end equipment
摘要
Abstract
Fiber to the home (FTTH ) with huge broadband supports all future business, and wins the final solution of broadband network. KTTH 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 lo the various needs of users, and comprehensively improves the quality of user service.关键词
