If you are thinking about having hands on the finest DWDM solution /DWDM supplier , for your business, or you need a way to ensure appropriate data transmission for your client’s business, you are at the right place.

You must have many questions regarding the DWDM solution and its suppliers, and it is imperative to have them answered to make a relevant decision.

This FAQ guide below features all such questions, and you will learn a lot of things by going through it, so let’s read below:

1. What are the functions performed by the DWDM system?

DWDM is a leading technology these days used in communication systems that are created using optical fiber. The DWDM leads to increased data transmission capacity and efficiency.

The primary function of the DWDM system is to carry out the task of multiplexing and demultiplexing the optical signals in one fiber optic. However, some of the standard key functions of the DWDM system are as follows:

  • The DWDM system combines many signals that operate at different wavelengths on one optical fiber. Hence, the data is transmitted over many streams through a single fiber.
  • DWDM systems can convert the wavelength of an optical signal which is an incoming one in different wavelengths, so that compatibility can be created that leads to optimizing the routing of the network.
  • Signals through the optical fiber travel at different long distances, and hence there is a need to ensure that the amplifiers are in place, which helps with this transmission, and the DWDM system carries out this task.
  • The receiving end of the fiber has a DWDM system that carries out the task of separating the signals which are combined in the first place, and this process is known as demultiplexing. It helps to extract the original signals back to their actual data streams.
  • It comprises OADM functionality which carries out the task of adding or removing the data streams without disturbing the network.
  • DWDM systems consist of dispersion compensation modules that ensure that the dispersion suffered by optical signals is mitigated and the signal quality is maintained.
  • DWDM systems even comprise optical monitoring capability, which helps measure the transmitted signals’ wavelength, quality, and power. These even help monitor the network operators to optimize and troubleshoot the system performance.
