Fundamentals of DWDM Technology

The early DWDM designs were built to fulfill the needs of the long-distance carrier. While that demand still exists, the need for DWDM on the local front is growing. If DWDM is the first step to optical networking, the Carriers have strong incentive to bring DWDM to metropolitan areas. Expect the momentum for WAN/LAN applications to accelerate over the next few years. The future looks rosy for the bandwidth enhancer of the fiber optics network, also known as dense wavelength division multiplexing (DWDM). With carriers looking for faster ways to transmit more data at cheaper costs, no other technology can live up to the challenge quite like DWDM.
