There are three readily-available and simple to install and use wave division multiplexing (WDM) technologies; 2-channel WDM, coarse wavelength division multiplexing (CWDM), and dense wavelength division multiplexing. These technologies can provide a carrier with a single extra wavelength or virtual fiber, 18 additional wavelengths, or up to 160 additional wavelengths. All of these technologies utilize the existing fiber in a carrier’s network.
