DWDM Networks

DWDM Networks over Long Distance Transmission

With the ever-increasing need for higher bandwidth, DWDM technology has been one of the most favorable optical transport network (OTN) applications. In this post, we will reveal DWDM-based network solutions over various transmitting distances as well as some suggestions for the DWDM networks deployment. DWDM Networks Basics As usual, let’s review some basics of DWDM networks. In this part, we…

Dense Wavelength division multiplexing

Why to Use DWDM System in MAN and What Are its Networking Schemes?

On account that DWDM (Dense Wavelength Division Multiplexing) technology can make full use of the huge bandwidth resources of the optical fiber, greatly increasing the transmission capacity of the system and reducing the transmission cost, the technology has been widely used in the large-capacity transmission of long distance network and backbone network. If DWDM technology is introduced into the metropolitan…

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…
