What is the DWDM Mux Demux Working Principle?
From the wikipedia we know that in electronics, a Mux Demux is a device that selects one of several analog or digital input signals and forwards the selected input into a single line.
A multiplexer of 2n inputs has n select lines, which are used to select which input line to send to the output. Multiplexers are mainly used to increase the amount of data that can be sent over the network within a certain amount of time and bandwidth. A mux is also called a data selector.”
An electronic multiplexer makes it possible for several signals to share one device or resource, for example one A/D converter or one communication line, instead of having one device per input signal.
Conversely, a demultiplexer (or demux) is a device taking a single input signal and selecting one of many data-output-lines, which is connected to the single input. A multiplexer is often used with a complementary demultiplexer on the receiving end.
DWDM data transmission technology: 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. This process allows for multiple video, audio, and data channels to be transmitted over one fiber while maintaining system performance and enhancing transport systems. This technology responds to the growing need for efficient and capable data transmission by working with different formats, such as SONET/SDH, while increasing bandwidth.
DWDM fiber working principle: DWDM fiber works by combining and transmitting multiple signals simultaneously at different wavelengths on the same fiber. In effect, one fiber is transformed into multiple virtual fibers. So, if you were to multiplex eight OC -48 signals into one fiber, you would increase the carrying capacity of that fiber from 2.5Gb/s to 20 Gb/s.
Currently, because of DWDM, single fibers have been able to transmit data at speeds up to 400Gb/s. As for DWDM mux/demux, the common configuration is 2CH, 4CH, 8CH, 16 CH, 32CH (32-Channel DWDM Mux/Demux), 40CH channels.
They are available in the form of Plastic ABS module cassette, 19” rack mountable box or standard LGX box. And no matter what kind of fiber connectors, like FC, ST, SC, LC etc, all are available on our website, and we also can mix connector on one device. We can provide you with the most suitable DWDM equipment.
