摘　　要：利用virial理论和数值模拟对色散管理光通信系统中的孤子传输进行了研究.结果表明,在普通光纤与色散补偿光纤的交界处,孤子幅度不连续,其幅度有所降低,但其形状保持不变.在小损耗光纤中传输的孤子,通过放大器幅度得到放大的同时,形状将自动得到恢复,可以稳定地、长距离不变形地传输,具有理想信息载体的特性.This paper studies optical soliton transmisson of fiber loss in soliton communication system with Virial theory and computer simulation. The result indicates where common fiber is joined to the dispersion compensation Fiber, the Soliton amplitude is decreasing, keeping the exact shape, but not continuous. Soliton Communicating in low Loss Fiber that being processed by a amplifier can resile by itself at the same time, transmit steadily, chronically, and always keeps the same shape. It possesses characteristics of perfect information carrier.
