Abstract

In this paper we describe the performance of the Multiplexer/Demultiplexer (MUX/DEMUX) in the Dense Wavelength Division Multiplexer (DWDM) technology based on arrayed waveguide grating (AWG). The accumulated crosstalk in large-scale AWG solved by the cascade-connection of small AWGs. We propose two branches of 64 channels each have two stages of AWG cascaded as second and third stages. We introduce an interleaver filter based on AWG to produce odd and even optical channels (64) as an input to each branch, which relax the system by doubling the space between channels.
