Frequency Division Multiplexing of Telecommunication Optical Modules
In telecommunications, frequency-division multiplexing (FDM) is a technique by which the total bandwidth available in a communication medium is divided into a series of non-overlapping frequency bands, each of which is used to carry a separate signal. This allows a single transmission medium such as a microwave radio link, cable or optical fiber to be shared by multiple independent signals. A. PrincipleThe multiple separate information (modulation) signals that are sent over an FDM system, such as the video signals of the television channels that are sent over a cable TV system, are called signals. At t. For, 20th century telephone companies used and similar systems carrying thousands of voice circuits multiplexed in multiple stages by. FDM can also be used to combine signals before final modulation onto a carrier wave. In this case the are referred to as : an example is transmission, where a 38 kHz subcarrier is used to sep.
