The relation between channelspacing and effect of XPM and FWM in DWDM system was analyzed, and a new solution for simulation of high speed and long haul DWDM system was derived.
A novel scheme is proposed, in which the aberrations in the off-axis holographic lenses used as demultiplexers are reduced to a low enough level for relatively small channelspacing.
本文提出了一种能够将解复用器用离轴全息透镜的像差减小到足以适用于相对较小的信道间隔的新方案。

The results also show that the channel capacity decreasinglyincreases with the antenna spacing and decreases with the coefficient K.
