The basics of Wavelength Division Multiplexing (WDM)

Wavelength Division Multiplexing (WDM) is a technology that increases the data-carrying capacity of optical fiber by allowing multiple streams of data to be transported using different wavelengths of light. The primary benefit of WDM technology is that it requires just a single optical fiber which, in most cases, has already been deployed. Therefore, it is a much less expensive option for expanding network capacity compared to installing additional fiber cables.
