wdm-opWDM - Wave Division Multiplexing

WDM stands for wavelength division multiplexing, which is a fiber-optic transmission technique that uses different wavelengths of light to send data over a single optical fiber. This allows a single fiber strand to carry multiple channels of data simultaneously.

WDM is a category of technologies that includes coarse wavelength division multiplexing (CWDM) and dense wavelength division multiplexing (DWDM). These two types of WDM are widely used in fiber optic networks to increase capacity, optimize resources, and meet the growing demand for high-speed data transmission.

WDM can also help consolidate connections by scaling bandwidth. While other high speed connections are becoming more common, optical carrier connections are still unmatched by their amount of raw bandwidth. WDM excels in WAN applications, which other high-speed connections are ill-suited for.
