DWDM is an acronym for Dense Wavelength Division Multiplexing. DWDM is a multiplexing technology based on optic fibers and is specifically designed to increase the bandwidth of existing fiber networks and infrastructure. This technology combines optical signals from different sources and multiplexes them over a single optical cable while ensuring that all data streams remain separate.
In DWDM, each individual light wavelength carries a separate optical signal. Here, the term “dense” refers to the fact that this technology can accommodate up to 80 different wavelengths, where each wavelength is about 0.8nanometer wide and propagates along with other optical signals without getting mixed.
To enable this multiplexing technology and increase the bandwidth of your fiber network, you need to buy DWDM Mux Demux devices. These devices allow you to combine (multiplex – Mux) different optical signals over a single optical fiber on one end and split (demultiplex – Demux) optical signals on the other end. As a result, the implementation of DWDM Mux Demux devices increases the capacity of a fiber network without the installation of additional expensive optical fibers.
How do DWDM mux demux devices improve fiber networks?
Fiber optical cables have become the backbone of high-speed internet networks and become a standard for the telecommunications industry. DWDM mux demux devices allow enormous amounts of data to traverse along a single network link by creating multiple virtual fibers, thereby, multiplying the capacity of the physical medium i.e. fiber optical cables.
Since data flows through different wavelengths, the streams or channels don’t get mixed up or interfere with each other. Hence, the use of DWDM Mux Demux devices ensures the integrity of data passing through them. It is the significant increase in network capacity due to DWDM technology that enables security partitioning or separate tenants in the same data center.
As it allows telecommunications and cable companies to handle so much data, DWDM mux demux devices have become immensely popular in the industry. Any company that runs densely populated data centers such as hyperscale cloud service providers or collocation providers with dense multi-tenant spaces can benefit from the purchase of DWDM mux demux devices.
How does a DWDM Mux Demux device work?
To understand the working of a DWDM mux demux device, you need to know how dense wavelength division multiplexing technology works. DWDM has tighter or narrow wavelength spacing that allows the adjustment of more channels onto a single fiber. It is better for systems where there are more than eight active wavelengths per fiber.
Since DWDM can finely divide the spectrum, it can easily fit more than 40 channels into the C-band frequency range. DWDM implemented in optical fiber systems today can achieve a throughput of 100Gbps. When DWDM is deployed in network management systems and add/drop multiplexers, carriers can adopt optically based transmission networks. This is what helps you meet the growing demand for increased bandwidth at a significantly lower cost.
