With the rise of bandwidth requirements, most individuals and business organizations seek a reliable internet service provider capable of providing their needs. Today, high-definition video and other types of digital information require different wavelengths without interference with one another.
Optical wavelength service addresses the need for high-quality bandwidth requirements. Most of the network providers and cloud service platforms nowadays offer such service to allow both individual and business organization clients to compete in a demanding online community.
While wavelengths may sound scientific to most people, it’s quite easy to understand how it works. An electromagnetic spectrum is a range of wavelengths of electromagnetic radiation. Light is a part of the spectrum.
What is Wavelength-Division Multiplexing (WDM)
Telecom systems use either DWDM or CWDM in their dense wavelength-division multiplexing (WDM). A wavelength-division multiplexing improves the bandwidth of existing fiber networks through an optical multiplexing technology. In a WDM, the different colors of light such as red, green, yellow, blue and other colors are transmitted through the air simultaneously. During the transmission process, the colors may mix. Fortunately, they can be separated with ease using a prism. The technique of separating a beam of light into its colors has been used since the early 80s. An upgrade of the technique in the late 80s paved the way for the development of the WDM with basic components.
The Two Types of Wavelengths
Modern telecom companies use either DWDM or CWDM systems. In the two systems, lasers are chosen and used with precise wavelengths, eliminating the possibilities of interfering with one another. Both CWDM and DWDM services are offered in wavelengths services. A Dense Wavelength Division Multiplexing or DWDM wavelengths are popular because of the simple technical requirements.
Advantages of DWDM
One of the main advantages of a DWDM system is its usable features. If you have a client with an old, existing link, there’s no need to remove and replace the current equipment. Another advantage of using a DWDM system is the use of lesser fiber cores. You don’t need more fiber cores to transmit and receive high capacity data on the internet when you use the system. For an easier network expansion, a DWDM system proves to be the best option for most organizations. Instead of using a 12 fiber core, you can use a single core fiber capable and divide it into multiple channels.
Disadvantages of DWDM
Just like with anything, the system also has its downsides. A DWDM system is an expensive choice for low channels. The complicated receivers and transmitters make it more expensive. A CWDM system will help you save more money if you have plans on using low channels.
Despite its disadvantages, a DWDM system proves to be a good option because of the continuous development in technology. The cost of the system can be lessened in the near future with the help of the current competition. The system can be a great asset in the future to everyone especially those in the business field.
If you want to know more about the pros and cons of DWDM and how your business can benefit from the technology, contact a professional network provider like GTT. The company is one of the best in the industry and has provided high-quality services at a reasonable price.
