WDM stands for Wavelength Division Multiplexing which is a technique of multiplexing (combining) multiple optical carrier signals of varying wavelengths via a single optical fiber. Hence, WDM makes it possible to allow communication in both directions through a single fiber cable. In this blog, we will discuss how a fused WDM coupler fits in the scenario of WDM networking solutions.

What does a fused WDM coupler do?

Technically, the device that is used for wavelength division multiplexing is called a fused WDM coupler. A fused WDM coupler is an optical device that allows you to combine optical signals of different wavelengths from different sources (transponders) so that they can be carried through a single optical fiber strand. In such a system, at the receiving end, a demultiplexer is used to separate the incoming beam into its original optical signals and then each of the optical signals is sent to the corresponding receiver.

What is the role of Fused WDM in the communication industry?

Fused WDM has long been the preferred choice for transporting large amounts of data between two sites. It increases the bandwidth to transfer different data streams at the same time over a single optical fiber network. This way, fused WDM technology helps maximize the usefulness of fiber and also helps optimizes network investments.

In other words, fused WDM has eliminated the use of multiple fibers for each and every service. A single fiber is enough and can be shared for several services. There is no need to rent or purchase several fiber cables. The cost of fiber rental or purchase has been known to represent a large chunk of networking costs. But, now, the use of existing fiber to transport multiple traffic channels provides substantial savings.

Previously, WDM systems were only used by carriers and service providers. Large-scale systems designed for national infrastructure made the systems too expensive and too complex for private network utilization. However, WDM technology has evolved rapidly.

Modern WDM networking solutions are within the reach of corporate enterprises, government organizations, and privately owned datacenters as well. Modern WDM technology is much simpler and more cost-effective than before.

Still, many organizations have yet to discover the benefits of implementing WDM networking.
