Frequency division multiplexing is a technique in which the available bandwidth of a single transmission medium is subdivided into several channels. There are three types of multiplexing are frequencydivision, wavelengthdivision, and timedivision multiplexing. There are variations of tdm such as optical time division multiplexing otdm. Fdm, wdm, tdm november 17, 2018 november 19, 2018 asif shaik generally, a communication channel such as an optical fiber or coaxial cable can carry only one signal at any moment in time. Some resources view these as types or forms of multiplexing. The analog multiplexing techniques involve signals which are analog in nature. There are mainly two types of multiplexers, namely analog and digital. Wavelength division multiplexing is divided into two types. Definitions of multiplexing multiplexing is the set of techniques that allows the simultaneous transmission of multiple signals across a single data link. In this type of multiplexing, signals are generated by sending different devicemodulated carrier frequencies, and these modulated signals are then combined into a single signal that can be transported by the link. The analog signals are multiplexed according to their frequency fdm or wavelength wdm.
