波分复用孤子通信系统容量研究

COMMUNICATION CAPACITY OF WAVELENGTH DIVISION MULTIPLEXED SOLITON SYSTEM

在波分复用（ＷＤＭ）孤子通信系统中，不同信道的孤子由于载波频率不一样而会发生周期性的碰撞，碰撞将引起孤子到达接收端时间的移动，这个现象限制着邻近信道的最小频率间隔和可以被复用的最大频率范围，即决定了ＷＤＭ孤子通信系统的最大通信容量。

In wavelength divesion multiplexed (WDM)soliton communication systems,solitons indifferent channels will collide periodically due to the difference of the carrier wave frequencies,whichresuIts in a shift of soliton arrivaI time. Such effect limits the minimum frequency difference of adjacentchannels and the maximum bandwidth which can be used for multiplexing,that is the communication Capacity.
