   Wave Division Multiplexing - WDM

Wave division multiplexing is a process of transmitting several distinct communication channels through a transmission medium (such as through a single optical fiber) via the use of a distinct separate wavelength (RF or optical frequency or "color") for each communication channel. Each such channel may be further subdivided into several logical channels via time division multiplexing or other methods.

This diagram shows how a wave division multiplexing over fiber operates. This diagram shows that there are several lasers operating at different optical wavelengths (different colors/frequencies). Each laser converts an electrical signal into a pulsed light signal. These optical signals (optical carriers) are combined by an optical multiplexer (lens) for transmission through the optical fiber. At the receiving end, the different optical carriers are separated by an optical demultiplexer (lens) and each optical carrier is sent to a photo-detector. The photo-detector converts the optical signal back into its original electrical form.
