Nowadays fiber optics takes all the responsibility of the data transmission and other networking with the help of advance technology in the fields of computer networking. Basically these are the fibers that are used to do communication between the networks and also help in delivering the data from one place to another. As fiber of the fiber optic is quite small and thin so, only specific amount of data can be transmit through fiber optics. But in the present era we can increase the amount of the data transfer through fiber optics by using the Dense Wavelength Division Multiplexing Technology or DWDM
Basically it is a technology that has been designed to upgrade the ability and the capacity of the fiber optics to transfer data from one place to another is called as the dense wavelength division multiplexing. Generally this technology comes from the WDS and it is used for the sake of faster communication and faster data transmission between two specific locations.
How DWDM Works?
The working of the dense wavelength division multiplexing is not similar to that of the technologies of data transfer but it is based on the enhancing the ability of the fiber optical cables that are used for the sake of data transmission. First of all the DWDM technology collect all the signals of the fiber optics and then trying to send them at a particular location at the frame of different wavelengths. This all working is carried out in the single thin fiber so, due to different wavelengths DWDM increase the capacity of the fiber optical cable to transmit data over them. With the help of DWDM user can increase the data transmission rate up to large extent. It is in such way if the users use the fiber optical cable for the sake of transmission having range of 1 GB per second. Then with the help of this new technology of dense wavelength they can enhance the capacity up to 8 GB per second because action of eight different wavelengths would involved with DWDM. So it helps the users to transfer data at the faster rate. Nowadays the faster rate that has been recorded by using DWDM over the fiber optics is more then 375 gigabytes per second. So it is one of the faster methods of communication.
Different type of networking systems based on the fiber optical cables and all the data transmission through these fiber optics is associated with the dense wavelength division multiplexing technology are referred to as the DWDM systems. There are different type of components used in the building of such systems and enhance their working over the network for the sake of transmission of data. Some of the important components that re used in the dense wavelength division multiplexing systems a4rre as follows
- A type of multiplexer based on the technology of DWDM called as Terminal multiplexer.
- DWDM line repeater.
- Optical multiplexing device.
- Different type of channels
- De multiplexer
These are some important components or the parts that are part of almost all the DWDM systems.
Benefits of DWDM:
As we know that dense wavelength division multiplexing is one of the faster and the easiest way to transmit data over network with the help of fiber optics. So it has many advantages that govern the modern technology. Some benefits are listed below
- It is the faster way to transfer data through fiber optics by increasing the power of the single fiber.
- New fiber cables are not required for this technology because it is applicable over old fibers.
- Save time and money.
