How is C-band wavelength division multiplexing divided
WDM systems are divided into three different wavelength patterns: normal (WDM), coarse (CWDM) and dense (DWDM). Coarse WDM provides up to 16 channels across multiple transmission windows. In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i. This technique enables bidirectional communications over one strand. According to the ITU-T standards, singlemode fiber with the band over 1260nm is divided into O/E/S/C/L/U six bands. WDM multiplexes two or more optical signals of different wavelengths onto a single fiber network, where they are demultiplexed and split into distinct data. WDM Wavelength Division Multiplexing is a transmission technology in fiber optic communication that uses a single fiber to transmit multiple optical carriers of different wavelengths simultaneously.

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).
