Bi-Directional-DWDM-Operation

An Overview of DWDM: Definition, Advantages and Applications

When capacity expansion takes place in traditional network transmission, Time Division Multiplexer(TDM) and Space Division Multiplexer (SDM) are adopted. Both of transmission networks use a single wavelength signal for data transmission. However, this transmission method does not make full use of optical fibers with a large capacity as the transmission medium, resulting in great waste. To deal with the issue, the…

WDM-multiplexer

Four Basic Elements in a WDM System

We know that fiber can carry more data over long distances than any other physical medium. That makes fiber a very precious material. And how to make the most use of your fiber plant becomes a question. So there comes Wavelength Division Multiplexing (WDM). Why Should We Deploy WDM? WDM can multiply your fiber capacity by creating virtual fibers. The…
