As providers densify their networks by pushing fiber deeper and adding small cells to meet the increased growth in demand for speed and capacity, coarse wave division multiplexing (CWDM) and dense wave division multiplexing (DWDM) offer two effective ways to increase the bandwidth of fiber by combining optical signals of different wavelengths on one fiber strand. It’s a practical, proven solution. This article helps you determine which WDM option is the best choice for your network.
