DWDM is Also Sometimes Called Wave Division Multiplexing?

With the introduction from the fiber optic communication industry by the challenges from the growing need for bandwidth and speed requirements. These requirements make the present limitations of the numerous kinds of communication systems are more prominent. Produce a new technology, which may solve the task faced by the communications industry.

DWDM system bandwidth demand brought about produce. Suppliers have how to effectively handle a definite boost in the request using a worried frown. The continual improvement from the optical fiber technologies have partially alleviated pressure on suppliers, also to open new regions of data and voice transmission, but as a result of incompatibility of numerous formats, in order that the optical fiber must be strictly tied to just one format . For those who desire to involve plenty of system suppliers, expensive new fiber is the reason a sizable share from the cost. So, just about the most promising program is specifically address high-speed DWDM technology (Dense Wavelength Division Multiplexing) came into being.

DWDM Mux module is really a technology that puts data from different sources together by using an optical fiber, with each and every signal carried concurrently alone separate light wavelength. Using DWDM, approximately 80 (and theoretically more) separate wavelengths or channels of knowledge could be multiplexed right into a light stream transmitted on one optical fiber. Each channel includes a time division multiplexed (TDM) signal. In a system with every channel carrying 2.5Gbps (billion bits per second), up to 200 billion bits can be delivered another by the optical fiber. DWDM can be sometimes called wave division multiplexing (WDM).

Since each channel is demultiplexed at the conclusion of the transmission back into the original source, different data formats being transmitted at different data rates may 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 inside optical fiber.
