In this paper, the authors introduced the cascading configurations of the large scale AWGs filters in the multiplexer/de-multiplexer based on different channels spacing designs under usages of the power full software named WDM- Phasar simulation. The cascade connection improved its capability in solving the accumulated crosstalk problem in AWG which it becomes the major limiting factor in the sensitivity of the array in long distance DWDM (Dense Wavelength Division Multiplexing) optical communication link. Acceptable results are obtained of AWGs filters with cascaded connection after using different channels spacing designs of 64 channels (0.708nm, 0.925nm and 1.233nm).
