What Is DWDM Technology ?

DWDM stands for Dense Wavelength Division Multiplexing, which is an optical multiplexing technology used to increase bandwidth over existing fiber optic backbones.

The “dense” here refers to the fact that DWDM technology supports more than 80 separate wavelengths, each about 0.8 of a nanometer (nm) wide on a single optical fiber.

Working Principle

DWDM technology increases the network capacity and makes efficient use of bandwidth.

The data from various different sources is put together on optical fiber in which each signal travels at the same speed on its own light wavelength.

At the receiver end, every channel is demultiplexed into original source, therefore different data formats with different data rates such as Internet data, Synchronous Optical Network data (SONET), and asynchronous transfer mode (ATM) data can be transmitted together at the same time through one optical fiber.

The transmission capability of DWDM is 4 to 8 times of TDM (Time Domain Multiplexing) and here EDFAs (Erbium doped optical amplifier) are deployed to boost the strength of signal.

The signal can be transmitted to more than 300 km before regeneration.
