How Does DWDM Work?

/in /by

Telecommunications keep evolving, and so does the way we watch television. According to the CTV in LATAM: The Future Forward report, 72% of Mexicans watch TV via streaming. And if we add that the trend is growing, we may deduce that we will be more connected next year than ever before. That is why infrastructure is becoming increasingly relevant to bring users these new services. One of the critical systems to achieve this is DWDM (Dense Wavelength Division Multiplexing). But what does DWDM mean? Well, we will talk about it in this particular article!

The Key to Today’s Telecommunications

Let’s start by saying that DWDM is optical fiber transmission. It is different because it is a transmission technique based on optical fiber that allows several light wavelengths. With this, it may deliver additional data through the same medium. As mentioned before, its main feature is that by spacing the wavelengths less, it may accommodate more channels in a single fiber. Its only downside is that it is slightly more expensive to implement and maintain. In the long run, however, it brings significant benefits.

Two of the primary uses of DWDM are long-distance networks and submarine cables, which may connect continents with submarine cables, such as those linking Europe and Asia.

Advantages of Implementing a DWDM Solution

  • The main advantage of DWDM in an optical fiber is the possibility of transmitting several signals using different laser wavelengths. To use DWDM efficiently, precise filters and control mechanisms are necessary to prevent interference between different waves. As with light pulses, they must be precise and accurate.
  • Another advantage is the possibility of adding more channels to the network in the future without the need for large setups. Therefore, in the long run, we may have significant cost advantages. In addition to the fact that information can be transmitted without interference regardless of the distance.
  • When looking for long-distance networks, DWDM systems are effective; thus, they solve the high demand of being constantly connected to a network.
