光纤中的材料色散

Material Dispersion of Light Cable

光纤色散是光纤通信的一个很重要的特性。由于光纤中存在色散,会使输入脉冲在传输过程中展宽,脉码之间产生干扰,增加误码率,这样就限制了通信容量和传输距离。

Light cable dispersion is a very important characteristic of light cable communication.Because of the dispersion existing in the light cable input pulse is made to be widen duringthe transportation proless, interference is produced, this limits communication capacity andtransportation distance.
