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 Key Component in DWDM System – Wavelength-Converting Transponder
The evolution of dense wavelength-division multiplexing (DWDM) systems is going on with an explosion in traffic and an increase in bandwidth-hungry applications for more multimedia services. Dense wavelength-division multiplexing, as an important technology in fiber optical network, is ideal for fiber optical-based solutions. By converting the operating wavelength of the incoming bitstream to an ITU-compliant […]
Three Key Components in a DWDM System
The explosive growth of Internet use and various applications of large bandwidth have increased the demands of information-carrying capacity in optical data transmission. DWDM, based on WDM (wavelength-division multiplexing) technology, has been developed to satisfy these demands. And this post gives a brief introduction of three main components in a DWDM system: MUX, DEMUX and […]
Advanced Optical Components – WDM Multiplexer
WDM Multiplexer is a device that uses Wavelength Division Multiplexing (WDM) technology to combine different optical wavelengths from two or more optical fibers into just one optical fiber. This combining or coupling of the wavelengths can be very useful in increasing the bandwidth of a fiber optic system. WDM multiplexers are used in pairs: one […]
