Overview: What does optical add-drop multiplexer stand for Functions of OADM Types of OADM (FOADM, TOADM) Applications of OADM
1,What does optical add-drop multiplexer stand for OADM is Optical Add-Drop Multiplexer, which used in WDM systems for multiplexing and routing different channels of light into or out of a single mode fiber. Its main function is to selectively drop or add one or multiple wavelength channels without affecting the transmission of other wavelength channels. The OADM device is one of the key devices of the all-optical network.

Wavelength Division Multiplexing (WDM) is one of the most common ways of using wavelengths to increase bandwidth by multiplexing various optical carrier signals onto a single optical fiber. It combines a series of optical carrier signals with different wavelengths carrying various information and coupled to the same optical fiber for transmission at the transmitting end. At the receiving end, optical signals of various wavelengths are separated by a demultiplexer. This technique of simultaneously transmitting two or many different wavelengths in the same fiber is called wavelength division multiplexing, or WDM.
