摘　　要：提出了改进的上行光环回技术和冲突检测技术以解决现有全双工CSMA/CDEPON方案中上行环回光功率损耗过大和冲突检测实现困难等问题 提出了一种半双工CSMA/CDEPON方案 通过理论推导和仿真验证 ,说明了虽然接入网系统中上 /下行业务量往往是高度不对称的 。The improved upstream lightwave redirection and collision detection techniques for the full duplex CSMA/CD EPON system are proposed.A half duplex CSMA/CD EPON system, in which both upstream and downstream traffic contends for the optical channel through CSMA/CD protocol, is also proposed. The throughput performance of the half duplex CSMA/CD EPON system is proven to be as well as that of the existing high speed half duplex Ethernet LAN by derivation and simulation.
