Abstract

One essential optical technology for multiplexing numerous different wavelengths toward a single optical cable is dense wavelength division multiplexing or DWDM. This article describes a dispersion compensating mechanism for a 32-channel DWDM system model. The optical link's pulse broadening effect is limited using the dispersion compensation approach. The 32-channel DWDM system employing DCF for NRZ Modulation Scheme at Different Bit Rate with Different Power Levels is investigated, evaluated, and simulated to solve the dispersion issue. Using an NRZ modulation technique and an erbium-doped fiber amplifier (EDFA) over a 40–160 km single-mode fiber transmission distance and an 8–32 km dispersion compensation fiber (DCF), the suggested model operates at 10–40 Gbps.
