【摘要】 对光交叉连接 (OXC)节点中采用半导体光放大器 (SOA)功率均衡技术的方案性能进行了理论分析。首先模拟计算了链路中引入SOA后的功率代价 ;然后逐一讨论了发射机消光比 ,信号码率 ,SOA的噪声系数对系统性能的影响 ;最后计算了OXC节点级联链路的误码率性能。从而为OXC节点和网络设计提供了理论分析和指导依据。更多还原

【Abstract】 Theoretical analysis on the performance of OXC nodes in which SOA is used as power equalization device is presented. The power penalty of link with SOA is simulated; and then the impact of some factors on system, including extinction ratio of transmitter, bit rate of signal, spontaneous noise factor of SOA, is discussed; finally the BER performance of cascaded OXC nodes with SOA based equalization module is given. All these provide the theoretical foundation for the design of OXC nodes and the optical network.更多还原
