DWDM (Dense Wavelength Division Multiplexing) is a combination of a set of optical wavelengths that can be transmitted with one fiber. This is a laser technology used to increase bandwidth on existing fiber-optic backbones. It enables optical fiber networks to transmit signals of several wavelengths simultaneously. In DWDM system, Mux/Demux are two indispensable components. How […]
DWDM MUX/DeMUX
Introduction to the Components Used in DWDM System
DWDM is an innovation that enables multiple optical carriers to travel in parallel in a fiber. DWDM devices combine the output from several optical transmitters for transmission across a single fiber. At the receiving end, another DWDM device separates the combined optical signals and passes each channel to an optical receiver. Only one optical fiber […]
CWDM & DWDM Mux/Demux Overview
As we all know, WDM (wavelength-division multiplexing) is a method of multiplexing a number of optical carrier signals onto a single optical fiber by using different wavelengths (colors) of laser light. It enables bidirectional communications over one strand of fiber, as well as multiplication of capacity. In a WDM system, a multiplexer (Mux) is used […]
A Comparison between CWDM and DWDM
Transporting a single data stream through an optical fiber can be costly and inefficient. Wavelength Division Multiplexing (WDM) technology can transmit multiple, independent data streams through a single optical fiber to better utilize the bandwidth of the given optical fiber. Each data stream adopts a different wavelength of light (also know as lambda λ) and […]
