What is Wave Division Multiplexing (WDM)?
Overview Wave division multiplexing (WDM) refers to an optical transmission technique where multiple optical signals are transmitted on a single optical fiber using diffe.rent wavelengths. In today's high-end WDM systems designed for long-distance communications, each optical signal (often referred to as a channel or a wavelength) can operate at up to 2.5 Gbps or 10 Gbps. Currently, available systems support from 32 to 64 channels and vendors are promising up to 160 channel systems in the near future. This enables a single fiber to carry more then 1 terabit/s of information. The term dense wave division multiplexing (DWDM) is often used to describe systems supporting a large number of channels, normally 16 or more. In contrast, the use of two or four channels on a fiber is sometimes referred to as "coarse" WDM.
