DWDM (dense wavelength division multiplexing)
wiredbrain.com
Dense wavelength division multiplexing (DWDM) is a technology that puts data from different sources together on an optical fiber, with each signal carried on its own separate light wavelength. Using DWDM, up to 80 (and theoretically more) separate wavelengths or channels of data can be multiplexed into a lightstream transmitted on a single optical fiber. In a system with each channel carrying 2.5 Gbps (billion bits per second), up to 200 billion bits can be delivered a second by the optical fiber. DWDM is also sometimes called wave division multiplexing (WDM).
Since each channel is demultiplexed at the end of the transmission back into the original source, different data formats being transmitted at different data rates can be transmitted together. Specifically, Internet (IP) data, SONET data, and ATM data can all be travelling at the same time within the optical fiber.
DWDM promises to solve the "fiber exhaust" problem and is expected to be the central technology in the all-optical networks of the future. DWDM replaces time-division multiplexing (TDM) as the most effective optical transmission method. Although TDM is the primary approach in today's networks, DWDM systems are expected to be tested and deployed in late 1998 and 1999.
