Abstract

Optical communication uses light signals for transmitting information from source to destination. Optical fiber communication has been more popular for long-distance data transfer in recent years due to various benefits such as low loss, low cost, simple amplification, minimal interference, and lightweight. A simple optical telecommunication system consists of a transmitter, a medium, and a receiver. Wavelength Division Multiplexing (WDM) is a significant improvement in optical communication. WDM is basically used for improving spectral efficiency and to handle more data from several clients. Normal WDM, CWDM, and DWDM are three types of WDM technology. DWDM uses the most denser optical channels in optical networking. Complete detail about all types of WDM is given. The optical spectrum used in the transmission of light signals is also discussed.
