Current solutions are limited by trade-offs between channel spacing, crosstalk, insertion. This paper presents the design and simulation of a high-capacity 32-channel Dense Wavelength Division Multiplexing (DWDM) system using OptiSystem software. This prototype delivers good Q-Factor and tolerable BER for 40Km that is considerably.
