Dense Wavelength Division Multiplexing (DWDM) Performance and Conformance Testing
Dense wavelength division multiplexing (DWDM) is a technology that uses multiple lasers to transmit many wavelengths of light simultaneously over a single optical fiber.
Each signal is modulated by different source data (text, voice, video, etc.) and travels within its own unique color band (wavelength). DWDM enables the existing fiber infrastructure of the telephone companies and other carriers to be dramatically increased.

Dense Wavelength Division Multiplexing (DWDM) Testing
At its simplest, a dense wavelength division multiplexed (DWDM) system can be viewed as a parallel set of optical channels, each using a slightly different light wavelength, but all sharing a single transmission medium.
This new technical solution can increase the capacity of existing networks without the need for expensive recabling and can significantly reduce the cost of network upgrades.

Dense Wavelength Division Multiplexing (DWDM) Tutorial
This tutorial addresses the importance of scalable DWDM systems in enabling service providers to accommodate consumer demand for ever-increasing amounts of bandwidth.
DWDM is discussed as a crucial component of optical networks that allows the transmission of e-mail, video, multimedia, data, and voice carried in Internet protocol (IP), asynchronous transfer mode (ATM), and synchronous optical network/synchronous digital hierarchy (SONET/SDH)...

Dense Wavelength-division Multiplexing Tutorial
Dense wavelength-division multiplexing (DWDM) revolutionized data transmission technology by increasing the capacity signal of embedded fiber.
This increase means that the incoming optical signals are assigned to specific wavelengths within a designated frequency band, then multiplexed onto one fiber.

WDM Technologies: Optical Networks
This revolutionary capability is being achieved with technology known as wavelength division multiplexing WDM). WDM technology relies on the fact that optical fibers can carry many wavelengths of light simultaneously without interaction between each wavelength.
Thus, a single fiber can carry many separate wavelength signals or channels simultaneously.
