摘　　要：本文以中国高速信息示范网(CAINONET)为对象,研究了在由OXC和OADM构成的光网络中,发送OTU输出口(光发射机)的主要性能参数,包括调制方式、中心频率偏移、发射功率、调制啁啾、光源谱线宽度、消光比等,对光网络性能的影响,并利用CAINONET仿真平台进行了仿真,得出了有益的结论,为CAINONET联网调试、扩充升级和光网络的标准化提供了参考和建议。Based on the China Advanced Information & Optical Network (CAINONET), this paper has studied the effect of the main performance parameters in the adding OTU output port (optical transmitter) on the performances of optical networks with OXCs and OADMs, including style of modulation, offset of center frequency, output power, modulating chirp, linewidth of laser, extinction ratio, and so on. Furthermore, some stimulation has been done by way of the CAINONET stimulating system. And the results achieved from simulating have provided references and advices for debugging and updating CAINONET and for making the optical network standards.
