ALSO CALLED: Wavelength-division Multiplexing, WDM, Dense Wave Division Multiplexing, Wave Division Multiplexing, Dense Wavelength Division Multiplexing, and D W D M
DEFINITION: Dense wavelength division multiplexing (DWDM) is a technology that puts data from different sources together on an optical fiber, with each signal carried at the same time 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. Each channel carries a time

The Impact of Carrier Ethernet on Service Providers
sponsored by Dorado Software
WHITE PAPER:
Mobile internet access and the explosive demand for high bandwidth services on mobile devices have created a pivotal point for service providers. Those providers that can meet the new demands while increasing efficiency will be able to increase their market share, while those that are not will lose ground. Read on to learn how to keep up.

DWDM DEFINITION (continued): … division multiplexed (TDM) signal. 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, Synchronous Optical Network data (SONET), and asynchronous transfer mode (ATM) data can all be travelling at the same time … DWDM definition sponsored by SearchTelecom.com, powered by WhatIs.com an online computer dictionary
