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。

Theoretical analysis on the performance of OXC nodes in which SOAis 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.
