Application of Dense Wavelength Division Multiplexing Technology
Dense Wavelength Division Multiplexing (DWDM): DWDM works with a greater number of channels than the traditional WDM. It can transmit over longer distances and is primarily used in large-scale networks such as those found in internet service providers and telecommunication companies. It is designed to maximize the capacity of fiber-optic cables by simultaneously transmitting multiple data signals on the same fiber. The authors have studied WDM-PONs with centralised lightwave source and direct detection, where a wavelength-reuse system is employed to transmit the uplink data by using a colourless transmitter at the optical network unit (ONU).
